I've run into a few problems when compiling vlc for FreeBSD from ports, typically it will compile o.k. but when I open it it won't show the interface or do anything (no errors, nothing). I'll run a few tests and then post the correct way to compile it.
That will be very welcomed. In the meantime, if you need help, don't hesitate to ask on the irc channel (#videolan on the Freenode network) or on the vlc-devel -AT- videolan.org mailing list.
