	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?
