My preference is that if my distro has a package that I want and the
latest such version (or a maintainer can be prompted to get latest
version in there), then I use the distro package.  Otherwise, I use
cabal-install.

This results in me using distro packages exclusively at home (since I
help maintain the Haskell packages for Gentoo) and cabal-install at uni
(since my machine has an old Ubuntu install on it that they're going to
update "any day now" :@ ).

Well, where did you get pivotal from?  If it isn't on Hackage but is
cabalised, you can download, unpack it and then within that directory
just run "cabal install".

No, the GHC mailing list is more towards development of GHC.
