category-extras clash with transformers
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 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.

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.

No, you're not totally screwed; you just need to bug xmonad-contrib and category-extras to fix their code. Edward

Edward I am wondering if upgrading from 6.12.1 to 6.12.3 will allow me to compile xmonad-contrib* and therefore, be ride of the old version of mtl and therefore, can install category extras.

No; since xmonad-contrib doesn't have bounds on the version of mtl being used, cabal-install will take the latest version. You need to use --constraint="mtl < 2". -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com IvanMiljenovic.wordpress.com
