Btw, you write

...does that mean you can't invoke `make` directly from within Emacs via
`M-x haskell-compile`?

I'm still trying to understand what you meant exactly by "too high an
overhead to getting started" with GHC development (as I don't consider
having to basically `apt-get install ...` (and possibly `cabal install
...` if your distribution doesn't have a recent alex/happy package) such
a high overhead to get your system able to compile a cloned GHC source
tree)

So I'd like to identify what you consider an overhead to improve the
underlying issues to make it easier for interested parties to get up and
running with GHC development.
