Figured out the problem - on Mac OS X, I had to install the Century fonts in a 
mac-y location for them to be found.

This seems buggy, as lilypond_datadir correctly points to a directory where the 
.otf font is hanging out.

It may be worth it for someone who knows more about fontconfig than I to check 
if font-config.cc is correctly adding the path.  In the meanwhile, I'll post a 
patch w/ more useful warning messages.

Cheers,
MS
