[fomus-devel] problems with 0.1.66

[David Psenicka]

Thanks for the post--the error is the reason why fomus tries to detect 
the lilypond version, the "def-music-function" changed a few times from 
version to version (I think now it's "define-music-function").  I'll 
make this user-settable (I'll try to update this by tomorrow).

Also, I think the reason why it can't get the version number is because 
it can't find the lilypond executable--I haven't tested it w/ 
OSX/lilypond 2.8 yet, so something might have changed, I'll have to look 
at this too.  There's a setting ("LILYPOND-EXE") for specifying the path 
to the lilypond executable so you can override fomus's default.  I think 
this should fix the problem until I get the next update out.  Let me 
know if you run across any other issues.
