Just to clarify something: this only occurs when --with-pmi is provided. We *never* link directly against libslurm for licensing reasons, and --with-slurm doesn't cause us to link against any Slurm libraries.
So the only impact here is that we would have to drop support for directly launching apps using srun, and require the use of mpirun instead. Regrettable, but my point is to clarify that this doesn't preclude use of OMPI under Slurm environments. Obviously, we would prefer to see it resolved, and that libpmi stand alone as an LGPL library :-) This goes beyond what Mike is requesting, which is to at least remove the hwloc dependency as PMI clearly doesn't require it.
