[Haskell-beginners] Error when running `cabal install cabal-install`

Indeed, I uninstalled libiconv by running the following command.

sudo port uninstall --follow-dependents libiconv

Then, `cabal install cabal-install` runs without a problem.

Hi MacPorts Users, Is there better solution to this problem? Please
see the original question regarding the conflict of MacPorts and
Haskell. (I don't what to use haskell from MacPorts as I want to keep
updated with the latest version of Haskell.)
