vlc fails to compile if the optional dependency on live is enabled (Bug #365)
checking for live555 version 1324598400 or later... no
configure: WARNING: liveMedia is missing or its installed version is too old:
Version 2011.12.23 or later is required to proceed.
You can get an updated one from http://www.live555.com/liveMedia .
configure: error: Update live555 or pass --disable-live555 to disable RTSP input support.
This seems to be due to the live spell not installing its headers to /usr/include/...
