Please take a look at  Most ports should be available for the 2.2, 3.x and 4.0
      branches, and many of them should work on 2.1.x systems as

       We also support the concept of a ``package'', essentially no
      more than a gzipped binary distribution with a little extra
      intelligence embedded in it for doing whatever custom installation
      work is required.  A package can be installed and uninstalled
      again easily without having to know the gory details of which
      files it includes.
       Use the package installation menu in /stand/sysinstall
      (under the post-configuration menu item) or invoke the
      pkg_add(1) command on the specific package files you're
      interested in installing.  Package files can usually be identified by
      their .tgz suffix and CDROM distribution people will have
      a packages/All directory on their CD which contains such
      files.  They can also be downloaded over the net for various versions
      of FreeBSD at the following locations:
       or your nearest local mirror site.
       Note that all ports may not be available as packages since
      new ones are constantly being added.  It is always a good
      idea to check back periodically to see which packages are available
