A few comments/suggestions:

• Making use of cblrepo sync removes the need to download Cabal files from hackage.
• Check out the versions command.
• The --patchdir patches is unnecessary, that's the default value.

My own usage goes something like this:

% cblrepo sync
% cblrepo versions -l <list of packages> > pkgs-to-add
% cblrepo add $(cat pkgs-to-add)
% cblrepo build $(sed -e 's/,.*//' pkgs-to-add) > build-order
% cblrepo pkgbuild --ghc-version 7.8.2 $(cat build-order)
% ./makeahpkg -- $(cat build-order)
% ./makeahpkg -a i686 -- $(cat build-order)
