[Haskell-cafe] Listing native package requirements based on cabal information

[David Thomas]

One option that just occurred to me would be to allow passing a script to
cabal that could be passed the extra-libraries (if any), and could install
if it knew the relevant OS packages (or NIX packages), or abort with a
cleaner error message.

Actually, wrapping ghc might be sufficient (though not ideal).
