I do have mpich 3.1.2 installed but I specifically installed mpich2 on request of another application that uses it. The version of mpich2 available from the Ubuntu repository is 1.4.1. I actually downloaded my mpchi2 1-5 from http://www.mpich.org/static/downloads/ in the understanding that this is the most recent available (last modified April 2013). How does this additional information change the picture?

Our current version is 3.1.3. The version you are using is years old so we'll have a hard time helping you fix any issues.
