They almost certainly are, for 2.1.1, since they are compiled from the same spec file.

It is confirmed not the case for R-devel, but is for 2.1.1 which is what the RPMs are for.

Although gcc 4.0.1 has helped, there are dozens of ongoing problems which seems squarely laid at the door of gfortran, as well as an appreciable performance loss. On AMD64 there are subtle incompatibility issues between gfortran and everything else (g77, gcc3 and gcc4) that make mixing C and Fortran code tricky at best.
