So lately when I use cabal to install something get

    Warning: Module `Prelude' is deprecated:
               You are using the old package `base' version 3.x.
               Future GHC versions will not support base version 3.x. You
               should update your code to use the new base version 4.x.

how do I implement cabal's advice?
