I have configured openMPI to work with the Intel C (icc) and C++

built all the single choice buffer fortran 90 bindings:

./configure --prefix=$HOME/openmpi CC=icc CXX=icpc F77=ifort FC=ifort
--enable-mpi-f90 --with-mpi-f90-size=medium

That all looks correct.

which works fine.  Ok.  Onto make all install.  Works fine too.  Now
when I try to compile the example hello_f90.f90 program, I get the
following error:

$HOME/openmpi/bin/mpif90 hello_f90.f90 -I$HOME/openmpi/include

FWIW, you shouldn't need that -I, but that *probably* shouldn't be causing your problem here (note that OMPI's F90 module file is installed into $prefix/lib, not $prefix/include).

Two things to check:

1. Are you using exactly the same ifort to build Open MPI as mpif90 is? I assume it is, but it's worth checking. You can run the following to see exactly what mpif90 will execute:

$HOME/openmpi/bin/mpif90 hello_f90.f90 -I$HOME/openmpi/include --showme

And then run it yourself, ensuring that your $PATH is set to get the exact same ifort, etc. I'm *guessing* that this is all correct, but it's worth checking.

2. Check to see if there is another mpi.mod installed somewhere in the compiler search path that is not the mpi.mod that you expect. For example, you might want to "rm -rf $HOME/openmpi" to ensure to have a 100% clean Open MPI install. And look elsewhere on the machine for mpi.mod that may be found in the compiler search patch before the Open MPI-installed mpi.mod is found.
