Well, all I can say is you're wrong.

Wine is an X11 program, no matter what *nix platform (Linux, BSD, OS  
X) you're running on.  It *has* to use the libGL provided by X11.  You  
don't have an understanding of how GL/GLX work under X11 on OS X - the  
GL libs under /usr/X11/lib are essentially wrappers around the the  
OpenGL framework.  However, you cannot simply link Wine directly  
against the system framework since the X11 interface that Wine uses is  
not provided by the system frameworks.  This is fact.

Please, understand something before commenting on it or saying that  
"Wine devs need to look at what the problem is."  There is no  
problem.  I am not a Wine dev, but I can get a working compile, with  
little to no legwork, on Snow Leopard.  I sent you what I use to  
compile and run Wine on Leopard/Snow Leopard; it works, I use it every  
day.  If you can't be bothered to do some research on how the pieces  
snap together, tough.  And if you want to distribute your packages:  
the minute someone asks you a question on the Wine/X11/OS X  
integration and you can't answer it, well double tough.
