Hi there.  I believe that you're facing this problem because MPI4PY
requires a build against shared libraries but your MVAPICH2 installation
is most likely static.

Can you confirm this by sending the output of `mpiname -a'.  If this is
the case you should be able to rebuild MVAPICH2 by adding
--enable-shared to the configure step.
