Thanks very much!  I was able to get it working after looking at
your example.  I now have a native code version of the example
named morph3d.

I'm using the fink versions of the OCaml modules.  Here are my
Makefile lines for anyone interested:

GLLIB = -cclib 
/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/libGL.dylib

morph3d: 

morph3d.ml
	ocamlopt -I +lablgl -I +lablgtkgl -I +lablgtk2 -o morph3d lablgl.cmxa 
lablgtk.cmxa lablgtkgl.cmxa $(GLLIB) gtkInit.cmx morph3d.ml

Yes, this is what I'm referring to.  The word on the Apple X
mailing list is to use the workaround and not worry too much
about it.  That's what I'm trying to do, but I'm a born worrier.
(Thanks for this link, too, BTW.)

Thanks very much for the help.  I really appreciate it.
