The gfortran build of Fortran library, as well as the .mod USE files,
won't work with ifort or PGI compilers. g++ built libraries ought to
work with sufficiently recent versions of icpc.
As noted above, it's worth while to rebuild yourself, even if you use a
(preferably more up to date version of) gcc, which you can use along
with one of the commercial Fortran compilers for linux.
