After the configure script has completed you can always tweak the
Make.inc file yourself.
An annoying problem exists with some versions of MPICH: the configure
script will set -DMPI_MOD, which is to say, the MPI call interfaces
will be resolved by using the MPI Fortran module. However usage of the
module may cause compilation to fail if coupled with the debugging
option -ggdb, because the compiler complains that it cannot find any
matching interface.
The solution: either take out the -ggdb option, or, if you really need
to debug, force -DMPI_H in place of -DMPI_MOD.
As a backup alternative, you can always choose a Make.inc.XXX file in
directory Make that fits your compilers, modify the paths to libraries
to match your installation and copy it to Make.inc in the top

KNOWN ISSUES.
An annoying problem exists with some versions of MPI: if the configure
script sets -DMPI_MOD the MPI call interfaces will be resolved by
using the MPI Fortran module.
However usage of the module may cause compilation to fail when
coupled with the debugging option -g, because the compiler complains
that it cannot find a matching interface for some of the
communication routines.
The solution: either take out the -g option, or, if you really need to
debug, force -DMPI_H in place of -DMPI_MOD.
SERIAL: We now provide an (experimental) option to run in serial
mode. This has only been tested with GCC but it should work
with the others as well. In serial mode you don't need the
