Further research shows that gs is not finding a dynamic library.  Console 
reports:

        dyld: Library not loaded: ./bin/../sobin/libgs.8.70.dylib

I tried to soft link from lib (which contains the dyld) to sobin, but that 
still didn't work.  gs also failed from command line.

However, if I did this in bash:

export 
DYLD_LIBRARY_PATH=/Applications/_AudioMusicRelated/LilyPond.app/Contents/Resources/lib:$DYLD_LIBRARY_PATH
 
Then the gs would work from the commmand line.

But I can't find a way to tell LyX to set up the DYLD_LIBRAY_PATH for calling 
gs.

I'm assuming that this is a bug in lilypond distribution, so I submitted a bug 
to them.

Other ideas?

Thanks!
