I always install ghcs under my home directory:
wget http://www.haskell.org/ghc/dist/7.6.2/ghc-7.6.2-x86_64-unknown-linux.tar.bz2
tar -xf ghc-7.6.2-x86_64-unknown-linux.tar.bz2
cd ghc-7.6.2
configure --prefix=$HOME/ghcs/7.6.2
make install
Then put $HOME/ghcs/7.6.2/bin in front of your $PATH.
You could also use:
hsenv --ghc=ghc-7.6.2-x86_64-unknown-linux.tar.bz2 for this:
http://hackage.haskell.org/package/hsenv
My colleague Jason just made a nice improvement:
https://github.com/tmhedberg/hsenv/pull/22
which allows you to do:
hsenv --ghc=7.6.2
which will automatically download the right ghc for your platform and
install it in a new fresh environment isolated from the rest of your
system.
