[petsc-users] which version of openmpi for petsc-3.1?

[Satish Balay]

One additional note with OpenMPI install:

OpenMPI defaults to installing shared libraries - but does not
use --rpath option within the mpicc wrapper - and requires user
to set LD_LIBRARY_PATH - so that mpicc is useable.

So make sure you do this before running PETSc configure [or install
openmpi static..]
