I am sending here because this could require intervention for some
packages and also to discuss a solution to prevent the problem in the
future.
Sometimes with newer versions of GCC there is a change in the version
for Fortran modules which is incompatible with older versions. All
packages providings Fortran modules (usually .mod files) must be rebuilt
when the module version is bumped. A possible solution to identify those
packages could be to provide a Fortran module ABI number in our gfortran
PKGBUILD and force packages with .mod files to explicitly depend on it.
Any thoughts on this?
Cheers,
Stéphane

Example with gfortran 4.8.0 and the openmpi package build with a
previous version :
# cat test_mpi_fmodule.f90
program test
USE mpi
end program test
# mpif90 test_mpi_fmodule.f90
test_mpi_fmodule.f90:2.4:
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
