Hi Johan,

Thank you for the tip. After a tiny manupulation at my PATH variable it works.

cabal install cabal-install will not install the latest version of
cabal-install due to a setting on Hackage (i.e. Duncan probably want
to wait before automatically changing everyone over). You need to give
the exact version:

    cabal install cabal-install-0.10.2
