Total newbie on haskell packages here. While upgrading to the last version of ghc and related haskell packages from testing, I've seen the following errors in the pacman log [2013-04-26 09:54] [PACMAN] upgraded ghc (7.6.2-1 -> 7.6.3-1) [2013-04-26 09:54] [ALPM-SCRIPTLET] ghc-pkg: cannot find package text-0.11.2.3 [2013-04-26 09:54] [ALPM-SCRIPTLET] Reading package info from stdin ... done.
