The recent update seems to have broken my box. After cleaning up everything (removing ghc), installing xmonad and xmonad-contrib will force downgrading some packages (such as haskell-x11). Then trying to install `haskell-stack` would fail.

Is this a known problem ?

No, I haven't heard of this before. First of all, removing ghc should trigger a removal of *all* haskell-* packages, including haskell-xmonad. Your wording above makes me suspect that you are trying to mix haskell package from [haskell-core] and [community]. Don't do that! :) Instead of installing xmonad and xmonad-contrib (both from [community]), install haskell-xmonad-contrib (from [haskell-core]). Please report back if that doesn't work. /M -- Magnus Therning OpenPGP: 0x927912051716CE39 email: magnus@therning.org jabber: magnus@therning.org twitter: magthe http://therning.org/magnus Finagle's Sixth Law: Don't believe in miracles -- rely on them.
