Two "None"s come from configure detection does not go well python windiws
(see the last.)

To go further I hacked configure as

I have met

I will install Numpy. 
However indtall.md in Pytave source.

Linked and tested with:

  * Python 2.7
  * Boost::Python 1.58
  * Octave 4.1 (development version)

Does Python 2.7 mean including extra modules?
What python extra modules required?
Do I have to also install SciPy?
