    Add cabal binaries to your PATH:
      export PATH=~/.cabal/bin:$PATH

    Run `cabal update` to initialize the package list.

    If you are replacing a previous version of haskell-platform, you may want
    to unregister packages belonging to the old version. You can find broken
    packages using:
      ghc-pkg check --simple-output
    You can uninstall them using:
      ghc-pkg check --simple-output | xargs -n 1 ghc-pkg unregister --force
    EOS
