[Openmcl-devel] Missing header(s) for OpenGL FFI?

Below is the backtrace but please keep in mind, this and the previous  
error I reported *only* occur with the new interfaces.  When I switch  
back to the older interfaces, the exact same code compiles without  
error.  Re: redefining something that the runtime needs... all of my  
code is in CL-USER (the only exception being a modification to  
ccl::sletify to add rect-to-nsrect) and I have not received any  
messages indicating that I'm redefining anything.  If this  
information isn't helpful, let me know and I will work on isolating  
the code which results in the error so that you can attempt to  
reproduce on your end.
