Basically, there are two ways of using pkgsrc. The first is to only install the package tools and to use binary packages that someone else has prepared. This is the pkg in pkgsrc. The second way is to install the src of pkgsrc, too. Then you are able to build your own packages, and you can still use binary packages from someone else.

4.1. Using binary packages

On the server and its mirrors, there are collections of binary packages, ready to be installed. These binary packages have been built using the default settings for the directories, that is:

  • /usr/pkg for LOCALBASE, where most of the files are installed,

  • /usr/pkg/etc for configuration files,

  • /var for VARBASE, where those files are installed that may change after installation.

If you cannot use these directories for whatever reasons (maybe because you're not root), you cannot use these binary packages, but have to build the packages yourself, which is explained in Section 3.2, “Bootstrapping pkgsrc”.

4.1.1. Finding binary packages

To install binary packages, you first need to know from where to get them. The first place where you should look is on the main pkgsrc FTP server in the directory /pub/pkgsrc/packages.

This directory contains binary packages for multiple platforms. First, select your operating system. (Ignore the directories with version numbers attached to it, they just exist for legacy reasons.) Then, select your hardware architecture, and in the third step, the OS version and the version of pkgsrc.

In this directory, you often find a file called bootstrap.tar.gz which contains the package management tools. If the file is missing, it is likely that your operating system already provides those tools. Download the file and extract it in the / directory. It will create the directories /usr/pkg (containing the tools for managing binary packages and the database of installed packages).

4.1.2. Installing binary packages

In the directory from the last section, there is a subdirectory called All/, which contains all the binary packages that are available for the platform, excluding those that may not be distributed via FTP or CDROM (depending on which medium you are using).

To install packages directly from an FTP or HTTP server, run the following commands in a Bourne-compatible shell (be sure to su to root first):

# PATH="/usr/pkg/sbin:$PATH"
# export PATH PKG_PATH

Instead of URLs, you can also use local paths, for example if you are installing from a set of CDROMs, DVDs or an NFS-mounted repository. If you want to install packages from multiple sources, you can separate them by a semicolon in PKG_PATH.

After these preparations, installing a package is very easy:

# pkg_add libreoffice
# pkg_add kde-3.5.7
# pkg_add ap24-php71-*

Note that any prerequisite packages needed to run the package in question will be installed, too, assuming they are present where you install from.

Adding packages might install vulnerable packages. Thus you should run pkg_admin audit regularly, especially after installing new packages, and verify that the vulnerabilities are acceptable for your configuration.

After you've installed packages, be sure to have /usr/pkg/bin and /usr/pkg/sbin in your PATH so you can actually start the just installed program.

4.1.3. Deinstalling packages

To deinstall a package, it does not matter whether it was installed from source code or from a binary package. The pkg_delete command does not know it anyway. To delete a package, you can just run pkg_delete package-name. The package name can be given with or without version number. Wildcards can also be used to deinstall a set of packages, for example *emacs*. Be sure to include them in quotes, so that the shell does not expand them before pkg_delete sees them.

The -r option is very powerful: it removes all the packages that require the package in question and then removes the package itself. For example:

# pkg_delete -r jpeg

will remove jpeg and all the packages that used it; this allows upgrading the jpeg package.

4.1.4. Getting information about installed packages

The pkg_info shows information about installed packages or binary package files.

4.1.5. Checking for security vulnerabilities in installed packages

The NetBSD Security-Officer and Packages Groups maintain a list of known security vulnerabilities to packages which are (or have been) included in pkgsrc. The list is available from the NetBSD FTP site at

Through pkg_admin fetch-pkg-vulnerabilities, this list can be downloaded automatically, and a security audit of all packages installed on a system can take place.

There are two components to auditing. The first step, pkg_admin fetch-pkg-vulnerabilities, is for downloading the list of vulnerabilities from the NetBSD FTP site. The second step, pkg_admin audit, checks to see if any of your installed packages are vulnerable. If a package is vulnerable, you will see output similar to the following:

Package samba-2.0.9 has a local-root-shell vulnerability, see

You may wish to have the vulnerabilities file downloaded daily so that it remains current. This may be done by adding an appropriate entry to the root users crontab(5) entry. For example the entry

# Download vulnerabilities file
0 3 * * * /usr/pkg/sbin/pkg_admin fetch-pkg-vulnerabilities >/dev/null 2>&1
# Audit the installed packages and email results to root
9 3 * * * /usr/pkg/sbin/pkg_admin audit |mail -s "Installed package audit result" \
	    root >/dev/null 2>&1

will update the vulnerability list every day at 3AM, followed by an audit at 3:09AM. The result of the audit are then emailed to root. On NetBSD this may be accomplished instead by adding the following line to /etc/daily.conf:


to fetch the vulnerability list from the daily security script. The system is set to audit the packages by default but can be set explicitly, if desired (not required), by adding the follwing line to /etc/security.conf:


see daily.conf(5) and security.conf(5) for more details.

4.1.6. Finding if newer versions of your installed packages are in pkgsrc

Install pkgtools/lintpkgsrc and run lintpkgsrc with the -i argument to check if your packages are up-to-date, e.g.

% lintpkgsrc -i
Version mismatch: 'tcsh' 6.09.00 vs 6.10.00

You can then use make update to update the package on your system and rebuild any dependencies.

4.1.7. Other administrative functions

The pkg_admin executes various administrative functions on the package system.

4.2. Building packages from source

After obtaining pkgsrc, the pkgsrc directory now contains a set of packages, organized into categories. You can browse the online index of packages, or run make readme from the pkgsrc directory to build local README.html files for all packages, viewable with any web browser such as www/lynx or www/firefox.

The default prefix for installed packages is /usr/pkg. If you wish to change this, you should do so by setting LOCALBASE in mk.conf. You should not try to use multiple different LOCALBASE definitions on the same system (inside a chroot is an exception).

The rest of this chapter assumes that the package is already in pkgsrc. If it is not, see Part II, “The pkgsrc developer's guide” for instructions how to create your own packages.

4.2.1. Requirements

To build packages from source, you need a working C compiler. On NetBSD, you need to install the comp and the text distribution sets. If you want to build X11-related packages, the xbase and xcomp distribution sets are required, too.

4.2.2. Fetching distfiles

The first step for building a package is downloading the distfiles (i.e. the unmodified source). If they have not yet been downloaded, pkgsrc will fetch them automatically.

If you have all files that you need in the distfiles directory, you don't need to connect. If the distfiles are on CD-ROM, you can mount the CD-ROM on /cdrom and add:


to your mk.conf.

By default a list of distribution sites will be randomly intermixed to prevent huge load on servers which holding popular packages (for example, mirrors). Thus, every time when you need to fetch yet another distfile all the mirrors will be tried in new (random) order. You can turn this feature off by setting MASTER_SORT_RANDOM=NO (for PKG_DEVELOPERs it's already disabled).

You can overwrite some of the major distribution sites to fit to sites that are close to your own. By setting one or two variables you can modify the order in which the master sites are accessed. MASTER_SORT contains a whitespace delimited list of domain suffixes. MASTER_SORT_REGEX is even more flexible, it contains a whitespace delimited list of regular expressions. It has higher priority than MASTER_SORT. Have a look at pkgsrc/mk/defaults/mk.conf to find some examples. This may save some of your bandwidth and time.

You can change these settings either in your shell's environment, or, if you want to keep the settings, by editing the mk.conf file, and adding the definitions there.

If a package depends on many other packages (such as meta-pkgs/kde3), the build process may alternate between periods of downloading source, and compiling. To ensure you have all the source downloaded initially you can run the command:

% make fetch-list | sh

which will output and run a set of shell commands to fetch the necessary files into the distfiles directory. You can also choose to download the files manually.

4.2.3. How to build and install

Once the software has downloaded, any patches will be applied, then it will be compiled for you. This may take some time depending on your computer, and how many other packages the software depends on and their compile time.


If using bootstrap or pkgsrc on a non-NetBSD system, use the pkgsrc bmake command instead of make in the examples in this guide.

For example, type

% cd misc/figlet
% make

at the shell prompt to build the various components of the package.

The next stage is to actually install the newly compiled program onto your system. Do this by entering:

% make install

while you are still in the directory for whatever package you are installing.

Installing the package on your system may require you to be root. However, pkgsrc has a just-in-time-su feature, which allows you to only become root for the actual installation step.

That's it, the software should now be installed and setup for use. You can now enter:

% make clean

to remove the compiled files in the work directory, as you shouldn't need them any more. If other packages were also added to your system (dependencies) to allow your program to compile, you can tidy these up also with the command:

% make clean-depends

Taking the figlet utility as an example, we can install it on our system by building as shown in Appendix B, Build logs.

The program is installed under the default root of the packages tree - /usr/pkg. Should this not conform to your tastes, set the LOCALBASE variable in your environment, and it will use that value as the root of your packages tree. So, to use /usr/local, set LOCALBASE=/usr/local in your environment. Please note that you should use a directory which is dedicated to packages and not shared with other programs (i.e., do not try and use LOCALBASE=/usr). Also, you should not try to add any of your own files or directories (such as src/, obj/, or pkgsrc/) below the LOCALBASE tree. This is to prevent possible conflicts between programs and other files installed by the package system and whatever else may have been installed there.

Some packages look in mk.conf to alter some configuration options at build time. Have a look at pkgsrc/mk/defaults/mk.conf to get an overview of what will be set there by default. Environment variables such as LOCALBASE can be set in mk.conf to save having to remember to set them each time you want to use pkgsrc.

Occasionally, people want to look under the covers to see what is going on when a package is building or being installed. This may be for debugging purposes, or out of simple curiosity. A number of utility values have been added to help with this.

  1. If you invoke the make(1) command with PKG_DEBUG_LEVEL=2, then a huge amount of information will be displayed. For example,

    make patch PKG_DEBUG_LEVEL=2

    will show all the commands that are invoked, up to and including the patch stage.

  2. If you want to know the value of a certain make(1) definition, then the VARNAME definition should be used, in conjunction with the show-var target. e.g. to show the expansion of the make(1) variable LOCALBASE:

    % make show-var VARNAME=LOCALBASE

If you want to install a binary package that you've either created yourself (see next section), that you put into pkgsrc/packages manually or that is located on a remote FTP server, you can use the "bin-install" target. This target will install a binary package - if available - via pkg_add(1), else do a make package. The list of remote FTP sites searched is kept in the variable BINPKG_SITES, which defaults to Any flags that should be added to pkg_add(1) can be put into BIN_INSTALL_FLAGS. See pkgsrc/mk/defaults/mk.conf for more details.

A final word of warning: If you set up a system that has a non-standard setting for LOCALBASE, be sure to set that before any packages are installed, as you cannot use several directories for the same purpose. Doing so will result in pkgsrc not being able to properly detect your installed packages, and fail miserably. Note also that precompiled binary packages are usually built with the default LOCALBASE of /usr/pkg, and that you should not install any if you use a non-standard LOCALBASE.
