On my OS X ppc/ghc-6.6 system, I found HsOpenGL.h in

	/opt/local/lib/ghc-6.6/include/HsOpenGL.h

(this is ghc-6.6 built from source with MacPorts.)  My guess is that  
your
compiler was built without OpenGL support.  If you downloaded a binary
compiler, you're stuck until someone adds it. Look at the output of

	ghc-pkg list

Do you see GLUT-* andfOpenGL-* ? If not, you do not have OpenGL support.

If you built your ghc from source, make sure you have enabled hopengl  
that the opengl
libraries are found (save the build logs and look in the  
configuration sections).

best wishes,
Greg
