I'm not sure who the best person is to receive these changes: We've been
encountering complications whe converting users to OFED 1.3 because the
scripts provided for configuring the shell (mpivars.sh and mpivars.csh)
don't update the library path. This can lead to MPI programs failing to
link or failing to run. The fix is to modify the spec files for the RPMs
for these packages so that they set the LD_LIBRARY_PATH as well as the
PATH.
The fix for MVAPICH-1.0.1 is this:
