This doesn't really have anything to do with Cabal as far as I know.
Hat comes with pre-translated libraries for a subset of the GHC
libraries.  It's true that the libraries that come with the compilers
may change in the future, partly due to Cabal, but I don't think this
is the reason that Hat doesn't come with all the libraries.  Hat
doesn't even use Cabal, AFAIK, but hmake.

Why is this a Cabal issue?  Are you interested in adding Buddah
support to Cabal?
