Sorry for these continued pains!

So PyOP2 imports cPickle elsewhere, so I think this module most exist.
 Plausibly the "six" module on your system is not sufficiently up-to-date.

Does the following fail:

python -c "from six.moves.cPickle import dumps"

If that works, I'm very confused, but I suspect it won't.

If it doesn't work, can you try installing an updated "six" module:

pip install --user six

and then go again.
