GhostBSD is based on FreeBSD and uses their packages. The difference is really just that GhostBSD makes FreeBSD "easier" (that is, more familiar), like what Mepis and Ubuntu did with Debian - make it simple enough for us poor common folk to enjoy the same freedom from costly evil greedy thieving proprietary OSes like Microsoft Windows.
If and when FreeBSD gets a port of Firedragon, it'll appear in our Software Station soon afterwards.
