That's a chroot, you should makeahpkg to build everything, including
ghc, to make sure your own system doesn't contaminate the built

No, what you need to do now is use cblrepo to create the source
packages, then you use makeahpkg to build them.

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)

There's a README that comes with cblrepo, that's a good place to
start, then there's also a README for HABS (http://is.gd/7b8ICP).
