####### Install Dependencies ###################################################
RUN apt-get -y update
RUN apt-get -y install build-essential curl zlib1g-dev libgmp3-dev libedit2
 
####### GHC 7.8.3 offical ######################################################
RUN curl -O http://www.haskell.org/ghc/dist/7.8.3/ghc-7.8.3-x86_64-unknown-linux-deb7.tar.bz2
RUN tar xvfj ghc-7.8.3-x86_64-unknown-linux-deb7.tar.bz2
RUN cd ghc-7.8.3 && ./configure
RUN cd ghc-7.8.3 && make install
RUN ghc --version

RUN curl -O http://hackage.haskell.org/package/cabal-install-1.20.0.3/cabal-install-1.20.0.3.tar.gz
RUN tar xvfz cabal-install-1.20.0.3.tar.gz

RUN rm -fr cabal-install-1.20.0.3*

## Ubuntu problems with install packages (previus installed)
sudo cabal --upgrade-dependencies install "name package" 

## For example: sudo cabal --upgrade-dependencies install github

cabal install --reinstall --enable-shared "package name"

There's issue in getting the files from curl since doing RUN curl -O http://www.haskell.org/ghc/dist/7.8.3/ghc-7.8.3-x86_64-unknown-linux-deb7.tar.bz2 actually return an HTML page instead of bzip
