Great!

I would advise against using GLUT.  I recommend GLFW-b.  You can get it
from Hackage. I've tested it on Windows 7, OSX, and Linux. It should just
work out of the box.

You need to find a copy of glut32.dll and put it into the same directory.
If you want to use GLUT, I would use the dll from freeglut. By the way, if
you want to use ghci with opengl you will need to start ghci with
-fno-ghci-sandbox.  Otherwise you will get weird crashes. This applies to
GLUT and GLFW-b equally.

I would use GLFW-b.

You can find some example code for haskell opengl here:
https://github.com/dagit/nehe-tuts

That version uses openglraw and glfw-b. If you want to use the non-raw
version of the api look at this version in the history of the repo:
https://github.com/dagit/nehe-tuts/tree/447f5471f3e7fe07b44dc5d2d87c4a95be35ce75

I hope that helps,
Jason
