I found a guide on how to compile numpy using ATLAS here:
http://www.scipy.org/scipylib/building/windows.html#building-atlas

does this help?

could we use one of the builds of numpy from anaconda
https://store.continuum.io/cshop/anaconda/ I believe their free version (
the one you get by default if you install it using conda)  isn't built
against MKL.
