[Haskell-cafe] Compatible problem with GHC 6.10.1

Hi all, I use Debian and GHC 6.8.2-7 Have install cabal, xmonad, gtk2hs with GHC 6.8.2-7 But when upgrade to GHC 6.10.1, i failed to install XMonad 0.8 and gtk2hs 0.9.13 I heard someone install success with develop version. So anyone success install XMonad and gtk2hs with GHC 6.10.1? BTW, i want to know the details compatible problem between 6.8 with 6.10? Is most libraries have compatible with GHC 6.10.1? Any suggestions? Thanks. -- Andy
