I'd recommend you fetch the latest changes I've made to the git repo.
There's a new pkgrel of GHC itself (7.4.1-2) as well as some fixes to
the patches.  Some extra instructions:

- After creating all the PKGBUILDs it's necessary to adjust the
  dependency on GHC (unless you modify `cblrepo` and build a new
  version of it), e.g. by executing something like

    for f in */PKGBUILD; do
      sed -e 's/\(.*\)ghc=7\.4\.1-1\(.*\)/\1ghc=7.4.1-2\2/' -i $f
    done

- It's not possible to record dependencies on tools in Cabal files,
  instead that is done in some of the patches.  Unfortunately this
  means that `clbrepo` can't produce a build order that is 100%
  guaranteed to work; a bit of manual tweaking of the ,,build-order
  file may be necessary.  I think the only tools in question are
  `alex`, `happy` and `gtk2hs-buildtools`.

Good luck ;)

Perl is another example of filling a tiny, short-term need, and then
being a real problem in the longer term.
