The problem you are experiencing is most likely because you have the
PathScale MPI libraries installed.  The major version of the MPI shared
libraries we ship is 2, while it's 0 for mvapich.  You appear to be
mixing code compiled against one set of MPI libraries with code compiled
against the other.

It is best to use the InfiniPath MPI libraries unless you specifically
need to be running an MPI app over Infiniband for some reason.
