I've installed mpich2 on my home machine to do development. Although
most of my MPI work has been in f77, I thought I'd build the libraries
with gfortran and expand my horizons a little bit.
However, when trying the example programs, I fumbled upon a showstopper.
mpiexec -n 2 ./cpi works fine, but
mpiexec -n 2 ./pi3f90 hangs with mpiexec using 100% of cpu
mpiexec -n 2 ./fpi hangs with mpiexec using 100% of cpu
Configure Options: --with-pm=gforker --enable-f90 --enable-f77
--enable-cxx F77=gfortran F90=gfortran
mpif90 --version gives

Is there anything I should be aware of, here?
