- Update math/py-kiwisolver to 1.2.0
- Add devel/cppy as setup dependency
- poudriere (11/12/13 i386/amd64) OK
- math/py-matplotlib also tested on 12amd64
cc thierry@ since math/sage depends on math/py-kiwisolver and I hope this update doesn't break math/sage (Due to the many dependencies, I can't test it now).
