Available to PC-BSD is its own PBI collection, FreeBSD ports, and FreeBSD packages. However, it is also possible to use the NetBSD pkgsrc system to build software. This is not (yet) a pre-configured feature, which means there are some special instructions to follow for this functionality to be enabled. This section will describe how to configure and use NetBSD pkgsrc from PC-BSD.
NOTE: Although these instructions seem complete and look polished, there is still some testing in progress, so be wary.

Contents

Setting things up

  1. Obtain the NetBSD pkgsrc tree by the following commands:

    # cd /usr/
    # ftp ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc.tar.gz
    # tar -xzf pkgsrc.tar.gz -C /usr

  2. FreeBSD stores its ports pkg database in /var/db/pkg/. It is therefore recommended that you use /usr/db/pkgsrc/ with the --pkgdbdir flag as below:

    # cd /usr/pkgsrc/bootstrap/
    # ./bootstrap --pkgdbdir /var/db/pkgsrc

  3. The NetBSD pkg tools and FreeBSD pkg tools have identical names. It is recommended to change the name of the NetBSD set to match 'bmake' by prepending a 'b' to each, as follows:

    # cd /usr/pkg/sbin/
    # mv pkg_add bpkg_add
    # mv pkg_create bpkg_create
    # mv pkg_delete bpkg_delete
    # mv pkg_info bpkg_info

    If you do not intend to use the FreeBSD ports tools, they can be moved out of the way as follows:

    # cd /usr/sbin/
    # mv pkg_add pkg_add.orig
    # mv pkg_create pkg_create.orig
    # mv pkg_delete pkg_delete.orig
    # mv pkg_info pkg_info.orig

    An example mk.conf file will be placed in /etc/mk.conf.example file when you use the bootstrap script.

  4. Add the location of bmake (/usr/pkg/bin) and NetBSD pkg tools (/usr/pkg/sbin) to the user's search path variable.
    Edit the file .cshrc in the user's home directory to modify the following line:

    set path = (/sbin /bin /usr/sbin /usr/bin /usr/games /usr/local/sbin /usr/local/bin /usr/pkg/sbin /usr/pkg/bin $HOME/bin)

  5. Add the PKG_PATH definition for the current version of pkgsrc (5.1) to the user's .cshrc file with the following line:

    setenv PKG_PATH ftp://ftp.netbsd.org/pub/pkgsrc/packages/NetBSD/`uname -m`/5.1/All/

  6. Obtain the vulnerabilities file:
    # /usr/pkg/sbin/pkg_admin -K fetch-pkg-vulnerabilities

    This prevents the non-fatal error below:

    WARNING: No /var/db/pkg/pkg-vulnerabilities file found.
    WARNING: To fix run: `/usr/sbin/pkg_admin -K /var/db/pkg fetch-pkg-vulnerabilities'.

  7. The vulnerabilities of some ports (ie Firefox) may prevent them from being built.
    Adjust /usr/pkg/etc/mk.conf to allow vulnerable programs to be built by adding the following line:

    ALLOW_VULNERABLE_PACKAGES=TRUE

Keeping pkgsrc up to date

The process for using tar files is very much the same as when obtaining them originally, except that the old tree must be erased first.

# rm -rf /usr/pkgsrc/
# cd /usr/
# ftp ftp://ftp.NetBSD.org/pub/pkgsrc/current/pkgsrc.tar.gz
# tar -xzf pkgsrc.tar.gz -C /usr


Next bootstrap pkgsrc again

Update the bootstrap-mk-files

  1. cd /usr/pkgsrc/pkgtools/bootstrap-mk-files/
  2. /usr/pkgsrc/bootstrap/work/bin/bmake update
===> Installing for bootstrap-mk-files-20111205
ERROR: bootstrap-mk-files-20111106 is already installed - perhaps an older version?
ERROR: If so, you may use either of:

ERROR:     - "/usr/pkgsrc/bootstrap/work/bin/bmake replace" to replace only the package without re-linking dependencies,

Using pkgsrc to build

Much like using the FreeBSD ports system, building with the NetBSD pkgsrc system is a rather simple matter of going to the location of the application within the pkgsrc tree, and then using bmake, for example:

%su -m
# unsetenv PKG_PATH
# cd /usr/pkgsrc/www/firefox/
# bmake install clean

Adding a NetBSD pkg

%su -m
# bpkg_add firefox

The above probably should simply work, or the NetBSD documentation would not mention renaming the FreeBSD pkg tools. However, for the moment, testing throws the following type of error:

pkg_add: Warning: package `firefox-3.6.16' was built for a platform:
pkg_add: NetBSD/x86_64 5.1 (pkg) vs. FreeBSD/x86_64 9.0 (this host)
pkg_add: 1 package addition failed
