Start with cleaning up your ah-ghc74 directory (you can use `git
clean` for that) and make sure you have `cblrepo` in your path.  Then
the following steps ought to do the job:

    $ cd ah-ghc74
    $ cblrepo build $(cblrepo list | cut -f1 -d\ ) > ,,build-order
    $ cblrepo pkgbuild $(cat ,,build-order)
    $ ./makeahpkg -x -- ghc $(cat ,,build-order)

Seems it built successfully.

I started with a cblrepo sync to initialize it. Here are the files/directories in my ah-ghc74 directory after running the scripts:

I made a copy of it for safety, then tried to install it:

sudo pacman -U ghc/ghc-7.4.1-1-i686.pkg.tar.xz

It says it cannot resolve the dependencies, namely ghc 7.0.3-2, but ghc --version gives: The Glorious Glasgow Haskell Compilation System, version 7.0.3.

Any clue? I did not update my arch for a while, maybe this is why.
