Comment (by Roland Haas):

Even with this fix the TOV example still fails because the container has both mpich-dev and openmpi-bin packages installed which made Cactus compile for MPICH and try to run using OpenMPI's mpirun. Issue created here: https://github.com/nds-org/jupyter-et/issues/7 which needs help to be able to upload a fixed container.
