I don't think there's a very large amount of cultural work - but some
to be sure.

We already have the following on OSX:

pip install numpy scipy matplotlib scikit-learn scikit-image pandas h5py

where all the wheels come from pypi.  So, I don't think this is really
outside our range, even if the problem is a little more difficult for
Linux.

I thought that Anaconda.org allows pypi channels as well?
