Yup, I copied those over from the GUB-built bundle.  I'm not quite sure how
they work, but it looks like the LilyPond executable looks for them on
startup, right?

Unfortunately, I don't quite see how to set the right path in those: an
.app bundle is movable, and while the Mac OS path resolver has a special
notation (@executable_path) for the path of the executable within that
bundle, it doesn't seem to put it into an environment variable in any
useful way.  I tried @executable_path in those pathnames, but it didn't
*seem* to work; OTOH, it changed enough behavior that further research may
be worth while.

I should say here that I don't know that much about Mac application
packaging; I'm doing this mostly because no one else seemed interested to
do it and I really want a 64-bit build.

Ah, thanks for the warning.  At this point I think it's all about
path-munging.
