Fink (MacOS X) package for lilypond 2.3.15

[Matthias Neeracher]

lilypond 2.3.15 is now available as a MacOS X fink <http://fink.sourceforge.net> package. 

- Set up your fink installation (/sw/etc/fink.conf) to use the unstable tree.
- Update your packages with fink selfupdate-rsync
- Type "fink install lilypond-unstable" to get lilypond 2.3.15

Lilypond and all its dependencies will be built.

[NOTE: In this release, I've managed to work around the ghostscript 8 issue (which appears to be a ghostscript bug), so lilypond works with any of the ghostscript packages again.]
