Sadly this may be rather expansive. Building software is not a simple
task. If we include cabal-get too then that pulls in networking, http,
and if we want to do security properly a bit of crypto too.

Yes. I agree.
Since GHC is currently statically linked, the set of libs that are
required to build GHC need not be related to the set of libs that come
with GHC by default.
