Jooil, most recent Xcode in Lion removes gcc-4.2, so you may want to install it from either from Xcode 4.0/4.1 or from http://r.research.att.com/tools/
The direct link is http://r.research.att.com/tools/gcc-42-5666.3-darwin11.pkg Also you can remove the Fortran you installed before (using gfortran-uninstall) since more recent Fortran is part of the above package.
