pkg delete on many ports and then reinstalled. Unfortunately vlc is now marked vulnerable, but it does build again with make DISABLE_VULNERABILITIES=yes. Of course this brings me back to the original question, how do I get a previous version of ports so I can build a previous version of vlc?
svn log -l [number of the commits you want to look back] /usr/ports/multimedia/vlc svn up -r [commit number you got before] /usr/ports/multimedia/vlc
