Comment 1 for bug 202974

Do the following:

1. Open register.sh file in the /usr/lib/libghc6-hgl-dev directory, for example in terminal

"sudo nano /usr/lib/libghc6-hgl-dev/register.sh"

2. Look for the line

"depends: base-3.0.1.0 array-0.1.0.0 X11-1.3.0"

and simply change the X11-1.3.0 to your version of X11 bindings for haskell (you can get this by writing in terminal "ghc-pkg list X11")

3. Save the file and execute it in terminal: "sudo bash regsiter.sh"

This should fix the problem.

Sorry for not using my Polish :) Perhaps some english speaking users encountered same problem.
