I built and tested pmemd with
pgcc 9.0-4 64-bit target on x86-64 Linux -tp k8-64e
serial and parallel
gcc version 4.1.2 20071124 (Red Hat 4.1.2-42)
serial only.
I can confirm that this patch corrected the link line oversight
and didnt cause problems.

The parallel tests had some hangs:
mpiexec -n 2 ../../bin/pmemd.MPI -O -i gbin -c md12.x -o mdout.dhfr.noshake

mpiexec -n 2 ../../bin/pmemd.MPI -O -i mdin -p NMA_scee+scnb_box.prmtop -c NMA_box.inpcrd -o variable_14_ntb1.mdout

and sander.MPI hung in this test
cd evb/poh_dbonds_umb_dg_UFF_9DG_nmpimd_full_TST-freqf && ./Run.evb

I havent investigated these.
