[Paraview] Cannot compile 4.1 on Ubuntu 12.04 x64 with OpenMPI 1.8.1

[Victor]

Thank you for the advice. I will attempt this tomorrow.

Regarding the openmpi path, I recompiled the system wide openmpi and it
indeed lives in /opt/openmpi-1.8.1. I no longer use an alternative openmpi
install path as that did not work out anyway.
