I have installed mtl-1.1.1.0 so that xmonad-contrib-0.9.1 would compile with GHC 6.12.1. http://permalink.gmane.org/gmane.comp.lang.haskell.xmonad/10603
Then I tried to installed category-extras-0.53.5, which clashed with transformers-0.2.2.0 for the Applicative/Monad instances for Either.
Is there any way out of this problem? Thanks for any pointers.
The instance in question is in the base package from GHC 7, which should avoid this problem of clashing orphans in the future. Unfortunately that doesn't help you -- I think both xmonad-contrib and category-extras need to be updated. _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe Thanks Ross, I just wish to confirm -- I'm totally screwed, right?
