Debian&HOpenGL, undefined symbol: glPixelStorei

Hi,

I'm trying to get HOpenGL working on a unstable debian box.
Since there were suitable packages available (ghc6, ghc6-hopengl)
I installed those. 
After trying to "ghci6 -package GLUT" I get the following error message:

Loading package OpenGL ... ghc-6.0.1: can't load .so/.DLL for: GLU (/usr/
X11R6/lib/libGLU.so: undefined symbol: glPixelStorei)


With packages for ghc5 this seems to work but I cannot get any example 
compiled.

The result for "ghc5 --make -package GLUT Planet.hs" is:

ghc-5.04.3: can't find module `GL' (while processing "Planet.hs")


Any help appreciated,
 Ville Tirronen
