This is a strange message. What happens is that DOLFIN can't find
Viper on your system and the Python plot script exits by calling

    exit(1)

For some strange reason, your Python believes that exit is a string.
(It is not for me.)

If you want to try the built-in plot, get Viper by

    hg clone http://www.fenics.org/hg/viper
    cd viper
    sudo python setup.py install

Yes, try Paraview or MayaVi.
