Problems with lilypond and lion?

[Alberto Simões]

Hello

I am using lion and having some trouble with Lilypond.

When I run it using the application icon under Applications, I get:

------------------------------------------------------------------------
LilyPond Error
An unexpected error has occurred during execution of the main script

ImportError: 
dlopen(/Applications/LilyPond.app/Contents/Resources/lib/python2.6/lib-dynload/objc/_objc.so, 
2): Symbol not found: _objc_sync_notify
  Referenced from: 
/Applications/LilyPond.app/Contents/Resources/lib/python2.6/lib-dynload/objc/_objc.so
  Expected in: /usr/lib/libobjc.A.dylib
------------------------------------------------------------------------

I usually run lilypond from the command line, and with Leopard, I had 
the following alias:

lilypond='DYLD_FALLBACK_LIBRARY_PATH= 
/Applications/LilyPond.app/Contents/Resources/bin/lilypond'

and it worked fine. With the new version, I get this other, different, 
error:

------------------------------------------------------------------------
dyld: Library not loaded: @executable_path/../lib//libstdc++.6.dylib
  Referenced from: 
/Applications/LilyPond.app/Contents/Resources/bin/lilypond
  Reason: image not found
Trace/BPT trap: 5
------------------------------------------------------------------------

Any hint? Anything I can do to solve this issue? Or the way to go is 
to.. argh... compile it?

Thank you,
ambs
