[Haskell-beginners] installing cabal 1.20 on linux mint debian edition (LMDE)

[Ovidiu Deac]

I'm trying to install cabal 1.20 like this:

I installed ghc and ghc-prof from apt repository so I got the following:
ii  ghc            7.6.3-5      amd64        The Glasgow Haskell
Compilation s
ii  ghc-prof       7.6.3-5      amd64        Profiling libraries for the
Glasg

Then I git cloned cabal and checked out Cabal-v1.20.0.0

Then I ran bootstrap.sh in cabal-install dir and I get the following error:

Using gcc for C compiler. If this is not what you want, set CC.
Using /usr/lib/gcc/x86_64-linux-gnu/4.8/collect2 instead.

What am I doing wrong here?
