ANNOUNCE: GHC 7.10.1 Release Candidate 1 - problem with latest cabal-install

[Johan Tibell]

Try

cabal install --allow-newer=base -j3 cabal-install

Once GHC 7.10 is out we might make another Cabal 1.20 release to bump the
upper bound on the base dependency if 1.20 is indeed compatible with the
latest base.
