Now I updated to ghc-7.6 and the method I already exposed just worked.

1. pacman -Rcs ghc
2. rm -r /usr/share/doc/ghc
3. pacman -S ghc cabal-install haskell-whatever

Those file wasn't in any package before, so point 2 is mandatory.

I also agree that deinstallling and reinstalling everything
Haskell-related is very bad, but this is far more comfortable than
using cabal and having 10 versions of every package installed (and
likely broken). As Haskell programs are statically compiled, I really
don't see the point in using such a tool like hsenv. I stick with the
archhaskell system.

Just my humble opinion,
