[GHC] Visual Haskell install error

[Simon Marlow]

Thanks for the analysis.  You can use the GHC bug tracker for tickets against 
Visual Haskell - just set the Component field to "Visual Haskell". 
Unfortunately we can't guarantee to fix anything promptly; Krasimir Angelov is 
the only person actively working on Visual Haskell, and he's been quiet recently.

Cheers,
	Simon
