The only library I had any trouble with was libmad for which I've  
submitted a patch.  My understanding is that if you get the latest and  
greatest of each library from their respective sources you run into a  
few more problems.

Very true.  10.4 and 10.5 are easy enough to do.  I never tried 10.3.9  
but shouldn't be too hard for PPC but that does kill the all in one  
build.

I've no problem with that as long as at the same time we can build  
Audacity as a universal from the command line with ./configure; make;  
or xcodebuild (my preferred option) for 10.4 and 10.5.
