I've been trying various options today. I had trouble getting MPICH to
compile on my machine and building OpenMPI gives the same result as
the Ubuntu OpenMPI.
I'm not 100% sure the Ubuntu OpenMPI is not being picked up. I removed
it first but needed to install it again since the boost package
depends on it. Do you use the package for boost or do you install that
locally too?
