| Talking about Ghostscript, I noticed that the latest version is GPL Ghostscript 9.00 released 2010-09-17 Wouldn't it make sense to update it in the lilypond distribution to benefit from the updates and ease the integration with other authoring software like LyX?

I was able to get this version of gs working in a shell by setting specific environment variables, but I could not find a way to set these variables for LyX, so I could not get instant preview (or DVI output) of lilypond scores within LyX. I was able to work around this by putting the lilypond bin path at the END of the path variable set in LyX -> Preferences. Then, LyX would pick up a different version of gs that didn't crash. Now it works fine. Again, I reported the bug to lilypond developers, and hopefully in a later version it will be addressed. Thanks!

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!

OK - got a bit further!
Changing the path variable didn't do it. Reviewing old emails again, I see that the PATH variable can be set in the shell OR in the Lyx -> Preferences -> Paths -> PATH Prefix
THEN, you need to do:
Lyx -> Reconfigure
(This was a step I was missing for a while.)
NOW, the lilypond example loads up without complaint.
BUT, I get an Apple app crash panel with the following error:
"gs cannot be opened because of a problem"
with some problem details looking like:
Process: gs [6477]
Path: /Applications/_AudioMusicRelated/LilyPond.app/Contents/Resources/bin/gs
Identifier: gs Version: ??? (???)
Code Type: X86 (Native)
Parent Process: dvipng [6476]
Date/Time: 2010-12-04 09:35:21.031 -0700
OS Version: Mac OS X 10.6.5 (10H574)
Report Version: 6 Anonymous
UUID: 219AD32B-CD4E-46DE-A36B-439CEBBA839D
Exception Type: EXC_BREAKPOINT (SIGTRAP)
Exception Codes: 0x0000000000000002, 0x0000000000000000 Crashed Thread: 0
Which to me suggests the problem is occurring when generating an png file.
This type of crash will come up when I:
View -> DVI
View -> HTML
View -> OpenDocument
However, the following work fine:
View -> PDF
Now it sounds like there is a problem with lilypond's gs itself.
Would you agree?
(I just upgraded lilypond "OS X" to 2.13.41-1, and the same symptoms occur.)
Thoughts?
Thanks!
