On Mac OS X 10.5, there is a fairly up-to-date /usr/bin/python.

I call this and other programs with scripts containing:
 exec /Applications/LilyPond.app/Contents/Resources/bin/midi2ly "$@"

Possibly (I haven't checked it), one might change that on 10.4 to:
 alias python='env python'
 exec /Applications/LilyPond.app/Contents/Resources/bin/midi2ly "$@"
and take down the python in Fink or MacPorts.

One simple way to create them is, in Terminal, to go to the directory  
where you want to have the script (I put it in ~/local/bin/ as do not  
want to clutter ~) and type
  cat > midi2ly
  exec /Applications/LilyPond.app/Contents/Resources/bin/midi2ly "$@"
  ^D
where the last is <ctrl>D. Then set it as executable by
  chmod +x midi.ly

Edit the script your using
  open -a 'My Text Editor' midi2ly

One needs to set the environmental variables, which can be done  
in .profile, or using the RCEnvironment from http://www.rubicode.com/Software/ 
.

My .profile file uses the text below, which enables using programs in / 
usr/local, MacPorts, Fink, and user, plus MacTex.

It might be useful to have a .bashrc file as well, as X11 doesn't  
read .profile (it doesn't make a bash login shell, see 'man bash'),  
which might contain:
  source ~/.profile
That is, it just reads .profile.

When all this is done, you have a midi2ly which works as as any other  
UNIX program.
