You can't install base or integer-gmp from cabal-install.  They are wired
into the compiler, and the only way to reinstall them is to reinstall ghc.
 In fact, finding a way to install ether from cabal-install will cause the
kind of breakage you're seeing.  (It's not supposed to be possible, at
least for base.  If at some point you installed integer-gmp from hackage,
you need to remove it; if you installed it into the global package
database, you really do have no choice but remove and reinstall ghc now.)

If you installed ghc as part of the haskell platform, then you need to
remove and reinstall that.
