You can't install it globally, so you'll probably need to build it
locally and insert that into your Python path.  You can do this by
running:

python2.7 setup.py build_ext -i

and then adding the current directory to PYTHONPATH.  There may be
more subtleties that I don't know of just yet.  The error you're
getting is a tricky one that I don't know how to get around.  Maybe we
should communicate off-list, come up with a solution and then come
back to the list.

You can install it into a local directory.

Maybe we should talk to consultants -- it may be worthwhile to build a
static Python and use that.  My lens account is not yet re-activated,
but should be soon.  I have also recently spent some time streamlining
the static build process for python/yt so I think we can use that.
