Problem installing
by Wink Saville 20 Sep '17

I successfully installing ghc, cabal-install and stack using the "official repos" but I when subsequently using "sudo pacman -Syu" I was getting weird errors that "haddock" files were missing. So I removed all the haskell stuff I'd installed previously (I hope) and then updated my pacman.conf to add the haskell-core repo [1] and ran "sudo pacman -Syu" all seems to be OK. I then installed ghc and that seems fine: $ sudo pacman -Syu ghc :: Synchronizing package databases... core is up to date extra is up to date haskell-core is up to date community is up to date :: Starting full system upgrade... resolving dependencies... looking for conflicting packages... Packages (1) ghc-8.0.2-1 Total Installed Size: 1135.84 MiB :: Proceed with installation?

My guess is that the conflict is because "ghc-libs-8.2.1-1" is being installed which is version 8.2.1 where as ArchHaskell hasn't updated to 8.2.1 yet.
