It'll be installed in the same prefix location as whatever package it
was installed as a dependency for. I usually type `pydoc numpy` to find
out which NumPy is picked up and from where.

Hmm, that's odd. Where is this coming from? Is this the system installed
one? It *might* also be your version of Cython that plays a role because
I *think* numpy.pxd comes with Cython.

I suspect there must be a difference in PYTHONPATH for the environment
you run firedrake in and execute the firedrake-clean script?
