These indicate that the gfortran you are using is producing 32-bit code.
I had success with the Snow Leopard gfortran binaries at High Performance Computing for Mac OS X.
Others have had success with versions supplied through other means.
Look through the recent Amber mailing list archive for Mac installation suggestions.

If you still have problems when you have update your gfortran, use "which gfortran" in Terminal.app to see if thr "wrong" gfortran has higher precedence in your $PATH.
