lablgtk2 + lablgl + native code on Mac

Folks:

I'm having a little trouble building a native code executable
for lablgtk2 + lablgl on my Mac (Intel, Mac OS X 10.5.4).  If
anybody has gotten this to work, could you describe what you did?
Bytecode executables work fine after a little trial and error
with the link step.

I have gotten native executables to work for lablgl alone, but
they are for the native GUI.  It seems that lablgtk2 needs to
work on top of X, which is confusing things (at least for me).
I would be happy with either the native Mac GUI or X interface.

The main difficulty (I think) is in some kind of Apple problem
with the OpenGL libraries.  There is a mysterious workaround that
works for lablgl, but I can't see how to apply it to this new
situation.

Thanks in advance for any help.
