Ok, I'm trying to build the haskell platform but getting this. Anyone know what the problem is? As far as I know I have all the development libs for OpenGL. I'm not sure what this means. I'm running Ubuntu 9.04 on a 64bit dual core AMD.

Preprocessing library GLUT-2.1.1.2...
Building GLUT-2.1.1.2...
Registering GLUT-2.1.1.2...
Setup: GLUT-2.1.1.2: dependency
"OpenGL-2.2.1.1-e949822dd9af14c1680857afb46ab567" doesn't exist (use --force
to override)

Error:
Building the GLUT-2.1.1.2 package failed
make: *** [build.stamp] Error 2
make: Target `default' not remade because of errors.

A lot of these kinds of modules were not actually part of GHC but
installed as part of GHC's "extralibs" packages (which is being replaced
by the Haskell platform).

You can get the first three modules by installing mtl and the last by
installing parallel, both of which can be found on Hackage.
