Often (though not always) with new GCC versions there is a new version for Fortran modules that is incompatible with old versions. An example error is here from the rebuild of the netcdf-fortran package:

  use mpi
      1
Fatal Error: Cannot read module file 'mpi.mod' opened at (1), because it was created by a different version of GNU Fortran

In the short term, we're going to need to get mpich2-1.5-2.fc19 tagged into the buildroot in order to rebuild netcdf-fortran and any other fortran module users.

We also really need a fortran module ABI virtual provides/requires I think to handle this properly.
