[Kwant] install mac os

Hi! I installed kwant 1.0.3 on mac os with pip install kwant Since this version, the new ones point to /usr/... instead /usr/local/... to find numpy libraries: kwant/_system.c:255:10: fatal error: 'numpy/arrayobject.h' file not found #include "numpy/arrayobject.h" and the installation fails. The correct path is of the form: /usr/local/lib/python2.7/site-packages/numpy/core/include/numpy/ etc. Best wishes, Alberto Verga <mailto:Alberto.Verga@univ-amu.fr> Université d'Aix-Marseille Campus St Jérôme, service 142 13397 Marseille cedex 20, France
