Sven,

For what it is worth, I built OpenGLRaw on my Mac (OSX 10.5.8) by simply 
removing the "extra-libraries: GL" line from the Cabal file - it was not 
necessary to add anything else.

If you leave the extra-libraries directive in the Cabal file, you can 
still build, if you must then provide explicit paths to the include and 
lib dirs, i.e.:

runhaskell Setup.hs configure 
--extra-include-dirs=/System/Library/Frameworks/OpenGL.framework/Headers/ 
--extra-lib-dirs=/System/Library/Frameworks/OpenGL.framework/Libraries

I tried adding "frameworks: OpenGL" to the Cabal file, but this made no 
difference, the configure step still complained about missing GL 
libraries.   This surprised me, in that I expected cabal to work with 
the OSX framework mechanism.  But I'm not an expert on either Mac 
frameworks or cabal - the above are simply what I've used and observed.

regards,
David
