I've got dynload_next working with PyOpenGL!

I used libdl's dlopen.c as a reference. The problem appears to be caused 
by the use of NSLookupAndBindSymbol(). I have switched to using 
NSLookupSymbolInModule() instead. I also commented out the quick return.

I have attached the diff file. It is also available at:
http://www.cs.unc.edu/~prastawa/macosx/dynload_next.diff

Can any of you try it out and make sure it doesn't break anything?
I haven't encountered any problems so far.

Marcel
