[TIP] Dependencies installation order with Tox

[holger krekel]

Hi Aaron,

gratefully, Jannis Leidel pointed me to this issue:

    https://github.com/pypa/pip/issues/25

which indicates and summarizes the problems you are seein.
The conclusion there is that this is a problem of scipy.

best,
holger
