[arch-haskell] haskell-safe in [haskell-extra] relies on ghc-7.4.2.1 ?

Hi, [haskell] seems to work fine with ghc 7.6.1 (the current ghc version in Arch repos) but my first try with [haskell-extra] has choked: sudo pacman -S haskell-safe resolving dependencies... warning: cannot resolve "ghc=7.4.2-1", a dependency of "haskell-safe" Actually my sole need is to install hoogle and I am trying to achieve this by using the provided repos. As I quickly realize that manual cabal installs are not a good option, I try to minimize them. Here I am just a bit surprised that the first package I try from [haskell-extra] fails because it expects another version of ghc ... Am I missing something or is it "haskell-safe" that should be fixed or removed  from the repository ?  Thanks for your help - PierreR
