Hmm, this one is a bit tricky since I don't (yet) have an OSX myself.
 From what I have a read the issues about SDL & CL are caused by OSX  
driving the SDL window in different thread than Lisp and I think  
Lispbuilder-SDL has some magic to overcome the problems.
A quick fix would be using LB-SDL for setting up the gl context and  
possibly handling the ui events. Naturally that would need some knowledge  
of the pal internals. If you are interested in trying that, replacing the  
PAL:OPEN-PAL and possibly PAL:UPDATE and PAL:HANDLE-EVENT with equivalent  
SB-SDL code might work.
In the long run it would of course be best to have some real fix for this.  
I'll do some searching and probably the least I can do is come up with an  
easy way to use PAL on top of LB-SDL.

Anyway, thanks for reporting. I'm very interested in getting PAL working  
on Mac.
