Generally, LAM/MPI needs to be compiled with the Fortran compiler you
intend to use with your application. Each Fortran compiler tends to have
a unique set of linking semantics / libraries needed / etc. and its a
bunch of work (and unsupported by the LAM/MPI team) to have a combination
of LAM/MPI built against one Fortran compiler and the application built
against another Fortran compiler.
Hope this helps,
