I've written a tool called cblrepo[1] which aims to make it possible
to maintain a consistent set of packages without having to rebuild
to find broken dependencies.  It is currently not used by anyone
involved in ArchHaskell, AFAIK, but it is surely possible to use to
speed up your ArchHaskell work (I know this from first-hand
experience).  I should point out that cblrepo can do more than this.
For ArchHaskell work I think the following are valuable features:

  - Maintain a consistent set of Haskell packages, checking
    dependencies when adding and upgrading packages.
  - An interface to follow Hackage:
    - Download the entire set of cabal files for all packages.
    - Check for updates to packages you maintain in the set.
  - An interface for adding/upgrading packages, takes a cabal file
    (filename), or URL for a cabal file, or a package name and version
    number (grabbed directly from Hackage).
  - Can show a list of all packages that need to have their revision
    bumped when a set of packages is upgraded.
  - Can show a list of all packages that need to be rebuilt when a set
    of packages are upgraded, the list is printed in a good build
    order.

I invented the term Object-Oriented, and I can tell you I did not have
C++ in mind.
