[Haskell-beginners] failed to install HTTP-4000.2.4 when executing `cabal install cabal-install`

Hi Friends, When I tried to update cabal-install today by doing `cabal install cabal-install`, I got the following message due to failure in compiling Network/HTTP/Auth.hs, here is a screenshot of the process ​ I am using Mac OS 10.8.4, and I installed haskell from homebrew. Does this mean something might have went wrong when I installed haskell? I have Xcode 5.1.1 and the latest command line tools installed. Does anyone know what might be going wrong? Thank you so much for your help! Best, Hengchu
