I think this test in Audacity needs to be changed just a bit. It looks like
LRN wasn't quite sure what was supposed to happen when start_time was defined.
In this case, start_time is set to 0 instead of the "undefined" value. I think
it should probably be changed to check for a non-zero start time in addition to
the existing check.

This is just that FFmpeg HEAD's libs were being found before the Ubuntu's, but
the Ubuntu ffmpeg command was be found before the FFmpeg HEAD's ffmpeg command.
 You could check your PATH and LD_LIBRARY_PATH environment variables to make
sure /usr/local/* comes before the /usr/* fellas.

Or just uninstall the FFmpeg HEAD stuff as you suggested.
