gfortran is an optional part of gcc. It will typically be installed in the same directories.
g77 was also an optional part of gcc, but since g77 is no longer updated, it will probably be some sort of separate tool now.
Why is g77 currently not supported? gcc-4.0 changed the front end interface for all languages in gcc. No volunteer or company stepped up to update g77 to the gcc-4.0 infrastructure, so it was dropped from the source tree. The Fortran-95 front end for gcc was under active development, so it has taken g77's place as the fortran compiler that is part of gcc.
