I was hoping that something a little less painful than a full from-source install is available/known.

At  http://askubuntu.com/questions/286764/how-to-install-haskell-platform-for-ubuntu-13-04
I find this -- basically the platform dependencies seem to have been made explicit.

sudo apt-get install ghc alex cabal-install happy libghc-cgi-dev libghc-fgl-dev libghc-glut-dev libghc-haskell-src-dev libghc-html-dev libghc-http-dev libghc-hunit-dev libghc-mtl-dev libghc-network-dev libghc-opengl-dev libghc-parallel-dev libghc-parsec3-dev  libghc-quickcheck2-dev libghc-regex-base-dev libghc-regex-compat-dev  libghc-regex-posix-dev libghc-stm-dev libghc-syb-dev  libghc-text-dev  libghc-transformers-dev  libghc-xhtml-dev libghc-zlib-dev

I was wondering if others know it as an ok approach or are there problems?
