The only hurdle for me for trying out (and maybe switching) to clozure on the mac platform is that I can't seem to get the cl-opengl package loaded.  I get the error:  "Trace/BPT trap" when I try to load that package.  (All other dependent packages like cffi, loaded successfully).

I am using ccl64,  version 1.5 on Darwin/MAC OS  (DarwinX8664).  Latest version of cl-opengl.

I believe I also tried it on the 32-bit ccl.  Same problem.  It looks like it only compiles a few source files in the cl-opengl package before it dies.

If someone can point out to me how I can trace this to provide more information on where it is crashing or maybe someone has run across this already with this particular package.

Thanks,
Kevin
