The Arch GHC package is not built against libedit (at least on x86_64) so the line editing packages aren't built. In the mean time, you can build your own ghc with editline support by: 1) Installing libedit: pacman -S libedit 2) Getting the GHC source: yaourt -G ghc if you don't have yaourt, download the files manually from the Arch SVN repo. 3) Building GHC: makepkg 4) Installing the package: pacman -U ghc-6.10.3-blah.pkg.tar.gz GHC's configuration script will pick up libedit and build the line editing package. Vegai: should libedit be added to the deps on the package? Cheers, Matt

Sorry for the confusion caused by my other reply. Since 6.10.3, ghc doesn't use an external readline/editline library. Install the package (haskeline perhaps?) using cabal or fetch it from the AUR. Matt
