Hi Anirban,
Thank you for your help. I believe you're right, I was coming to the same conclusion myself.
One thing however, I have Mountain Lion with Xcode 4.6 installed for iOS development. As far as I understand it, gcc 4.2 is not included with that version of Xcode.
Don't I have to install gcc-42-5666.3-darwin11.pkg to get gcc 4.2 and gfortran? http://r.research.att.com/tools/ states that gfortran-lion-5666-3.pkg is for those who already have gcc 4.2 installed, but you seem to have it working ?
Additionally, can you tell me if installing these packages has any adverse effect on your Xcode development environment (llvm-clang, iOS development etc)?
Best regards
John
