I have similar problems. I would have expected that
   ./configure --enable-mpi
--with-mpi-fc=/usr/lib64/mpi/gcc/openmpi/bin/mpif90 FC=gfortran
would work, but it does not:

checking for a native MPI support... no
checking whether to build parallel code... no

which is not surprising as not the MPI compiler but the normal compiler
is used:

configure:10981: gfortran -o conftest    conftest.F90  >&5
Error: Can't open included file 'mpif.h'

Note: mpif90 is at a bit strange location on openSUSE (see above) to
allow for multiple MPI installations installed at the same time.


At the end I was configuring once for abinis and the rest, and once for
abinip using:

./configure FCFLAGS="-O2 `mpif90 -showme:compile`" --enable-mpi
LDFLAGS="`mpif90 -showme:link`"

(Whether -showme:* works, depends on the MPI library; I'm using OpenMPI
which offers this option.)


By the way, I also don't understand why there is not give YES for:

configure:8697: checking if we are using the GNU Fortran compiler
configure:8720: result: no

As I use:
$ gfortran --version|head -n1
GNU Fortran (GCC) 4.2.1 (SUSE Linux)
