Third-party Python packages implemented in C

Downloading and installing packages for IBM's Python is described here:

https://www.ibm.com/developerworks/community/wikis/home?lang=en#!/wiki/IBM%20i%20Technology%20Updates/page/Downloading%20packages%20using%20the%20pip3%20command

As noted on that page, some packages contain (or are dependent upon) C
or C++ code, which much be compiled on the i (in PASE). Have any of
you tried installing such packages? Would you be willing to?

Some examples of popular Python packages that rely on C/C++ are

NumPy
lxml
PyCrypto
Pillow (successor to PIL)

(Of those, I'm most immediately interested in PyCrypto. That and lxml
are the ones which would be of the most obvious use for typical IBM
midrange shops.)

The reason I'm not just doing this myself is that I actually don't
have IBM's Python installed, nor do I have any C compiler installed in
PASE, and I would have to go through a request process to get these
installed. And maybe you can see where I'm headed with this: If it
turns out that these packages are pip-installable, that greatly
strengthens my justification for the request.
