[Numpy-discussion] problem with numpy.distutils and Cython

[Lisandro Dalcin]

The monkeypatching below in your setup.py could work. This way, you
just have to use numpy.distutils, but you will not be able to pass
many options to Cython (like C++ code generation?)

from numpy.distutils.command import build_src
import Cython
import Cython.Compiler.Main
build_src.Pyrex = Cython
build_src.have_pyrex = True
