/lib vs. /lib64? It depends on the version of `libtool` on the machine IIRC.

I am sharing /opt/openmpi-1.7.4 via NFS but there does not seem to be a way to tell the nodes where OpenMPI is located when using non-interactive SSH (using secure key login). SSH does not seem to parse .bash_profile so I do not know how to tell the jobs on the nodes where to find OpenMPI except by starting the job with /opt/openmpi-1.7.4/bin/mpirun.
For a non-interactive login ~/.bashrc is used.
