Unfortunately this characterization was perhaps a bit optimistic. Sadly
the errors provided by GHC when used with an older Cabal aren't any
better in -rc2 than they were in -rc1. I've opened #11558 to track this
issue.

Users seeing unexpected missing interface file errors need to update
Cabal and cabal-install from git. This must be done using GHC 7.10 at
the moment as some of Cabal's build dependencies lack a build plan with
8.0.

    $ git clone git://github.com/haskell/cabal
    $ cd cabal
    $ cabal update
    $ cabal install Cabal/ cabal-install/

Cheers,

- Ben
