BSD alternatives, administration level

Many programs are ported to GNU/Linux, before they are ported to FreeBSD, so here is an inconclusive list of BSD style equivalents of GNU programs. GNU licensed programs are generally allowed to be used in pkg and ports, but BSD and compatible licensed programs will be listed. Not always can a BSD dependency be a drop-in replacement for a GNU or other style of dependency without patches. Alternative programs are not always immediately compatible either, and it may have to be tested for compatibility. The subject may include other non-proprietary, including MIT and GNU, licensed programs.
