[xmonad] XMonad-contrib installation problem

[wagnerdm at seas.upenn.edu]

Having a directory-1.1.0.0 in your user package database and in your  
global package database looks a bit fishy. If it were me, since there  
are so few packages installed at all, I'd probably do some sequence  
like this:

1. rm -rf ~/.ghc # get a clean slate
2. cabal install xmonad-contrib # this will pull in xmonad all by itself

Let us know if that doesn't work, or if you want a more precise fix.  
(rm -rf ~/.ghc is a pretty big hammer, but it can probably be refined  
if you don't mind learning a bit about Haskell's dependency management.)
