That is very useful!

And I just found out what the difference was between you and me: I 
didn't specify the "--enable-external-libs" configure option. I simply 
removed the "--disable-external-libs" option instead, wrongly assuming 
that this enables external libraries (vorbis, flac). It doesn't, so I 
wasn't getting any errors.
