this bug has been fixed about two weeks ago; it should no longer occur
with the current PKGBUILD files. An easy way to get your system back in
shape is to un-install all Haskell packages by running

  pacman -R --cascade ghc

..., then clean up the package database with

  rm -rf /usr/lib/ghc-6.12.3

..., and finally re-install those packages that you'd like to have. The
procedure is a little awkward, I'm afraid, but you won't ever have to do
it again, just this one time. ;-)

Take care,
