ok. Now I understand. As you suggest below, putting these into a library
would be far more sensible.

could build as usual.  This would be lame, though, since Vorbis would have
yet another dependancy (although this is mitigated by the fact that this
would probably make other GNU software work better).

Vorbis does not have another dependency. Libao does (and will continue to
unless someone contributed dynamic loading code for multiple platforms).
vorbis doesn't need libao - indeed, only ogg123 does. Given that the
chances of ogg123 working on OS X are slim anyway (it doesn't even build on
solaris, which is far closer to linux than OS X is), you might not want to
bother with this at all.
