- upgrade to latest 3.1 version of Pathscale (3.1-231.14750 or later)
- upgrade to 1.2.5 of openmpi
- make sure you are using blacs 1.1.patch3
- make sure you are using scalapack 1.8.0

This combo is the first that i have seen pass the blacs and scalapack
selftests. Any earlier version combo of pathscale/openmpi used to fail
the blacstests horribly.
