I found the examples included in the source code very helpful.
http://darcs.haskell.org/packages/GLUT/examples/
I think the RedBook directory contains the most examples.
If you want to know the modules a package exports you can use, e.g..
$ ghc-pkg describe OpenGL
name: OpenGL
version: 2.2.1
license: BSD3
copyright:
maintainer: [EMAIL PROTECTED]
stability:
homepage:
package-url:
description:
category:
author:
exposed: True
exposed-modules: Graphics.Rendering.OpenGL.GL.Antialiasing
Graphics.Rendering.OpenGL.GL.BasicTypes
[...]
These are the full names of the modules, you have to use to import
them. For GLUT there's one module that re-exports all others, iirc.

I got the packages imported by using the full names (Graphics.UI.GLUT
and Graphics.Rendering.OpenGL.GL). The compiler doesn't recognize
names like WindowPosition and WindowSize, but I assume that's because
the code is so out of date (this is from the 2001 tutorial). I'll
look in the docs to see how to procede.
