That's because RC3 happened shortly before Cabal got properly tagged,
and was rather an internal transitional versioning to make sure
RC3 clearly marked that it didn't ship with what was available on
Hackage as (fwiw, if you build with the current ghc-7.10 branch
tip you'll end up with the uploaded

I'm sure cabal-install can be modified to build-depend on those
conditionally (via cabal conditionals)...
