Thanks Ross!

Sent.

I also realised if we're encouraging people to use:

        build-depends: base >= 3 && < 5

then cabal should be picking base 4 in this case. That was ticket
http://hackage.haskell.org/trac/hackage/ticket/485 which I've just now
implemented, but it need testing, back-porting and releasing as
cabal-install-0.6.4.
