OK, I've committed the changes above to the GLUT package repository. Could you 
(or somebody else) post the corresponding sections of a working OpenGLRaw and 
GLURaw Cabal file for OS X, please? I guess that they should both use dlsym(), 
too, and both should contain a "framework: OpenGL" line instead of an extra-
libraries: line on this platform, correct?
