I've attached a patch; please check it.

OK, I had to ask as there seemed no discussion anywhere of what this 
did. 

FFmpeg 0.6.2 is certainly still working fine in Audacity on Windows 
and Mac (and 0.5 still works too on Windows).

Understood, but isn't it the case that if you try to launch 
Audacity having configured it with --disable-dynamic-loading, 
but either LAME or FFmpeg are missing, then Audacity won't 
launch? 

Richard called these "hard dependencies".
