Hi Travis,

I'm quite new to python, so I don't have much knowledge of all 
dependencies between scipy, mumpy, mumarray, ... and I don't think that 
I'm able to compile full python on my own. Compilling from source seems 
much easier on linux than on win.

Probably it is the best to change to enthought python than picking up 
all packages on my own.
