You don't want to remove that "fake" GCC, it's part of Xcode. You can install a real GCC using home brew, which will include gfortran. It will install to a different location, and you'll be able to choose whether to run the "fake" GCC (i.e. Clang) or the real one (from home brew) using the full path to the binary, or by editing the PATH variable in your environment.
