Dear John,
You need to compile open MPI with the same Fortran compiler as you use to
compile Amber. I suspect that you didn't manually specify FC= when building
openMPI and so it used either g77 or gfortran.
All the best

Subject: AMBER: Building parallel Amber 9.0

I am trying to build a parallel install of Amber 9 on an SGI Linux system
with 4 processors. I properly installed the open-mpi utility. I use the
"configure" with "ifort_ia32", which I think is appropriate for my system. I
then do a "make clean" as recommended. When I try to install the package, I
get the following error messages (many of these):
force.o (.text + 0x273b):In function 'force_':
:undefined reference to 'mpi_bcast_'
.........many such complaints
make [1]: *** [sander.MPI] Error 1
make [1]: Leaving directory '....../src/sander'
make: *** [parallel] Error 2
This seems to point to a problem with open-mpi, but that package seemed to
install without errors. Can someone point me in the right direction?
