Message-ID: <6305cedc-8333-a228-10f7-38a8c2869...@haskus.fr> Content-Type: text/plain; charset="utf-8"; format=flowed Using haskell packages provided by ArchLinux is a pain (cf https://wiki.archlinux.org/index.php/Haskell). You have to tweak ~/.cabal/config, etc. I would recommend using `stack` as it manages ghc installations itself. You could also use ghcup+cabal-install.
