I have no idea what you mean by "file list", but everything else is exactly as it should be. It's GNU Fortran 4.2.4 compiled in Apple's gcc 4.2.1 (build 5666.3) branch - which is what Xcode 4.1 is (see gcc-4.2 --version).

You can use either (as the post said). The differences from the CRAN Fortran are the same as for any of the Leopard and Snow Leopard Xcode add-ons, nothing changed since.
