[SciPy-User] numpy.test() fail mac with homebrew python 2.7

[Adam Schneider]

Hey Ralf, thanks for the quick response.

I tried a clean install, but scipy still fails to install with this error:
numpy.distutils.npy_pkg_config.PkgNotFound: Could not find file(s)
['/usr/local/lib/python2.7/site-packages/numpy/core/lib/npy-pkg-config/npymath.ini']

It looks like it is the same issue that people are running into here:
http://stackoverflow.com/questions/12574604/scipy-install-on-mountain-lion-failing

Trying the workaround suggested on SO and installing numpy from top of tree
allows scipy to install from pip, but numpy.test() fails the following test:

FAIL: Test numpy dot with different order C, F

Should this be a known fail? Also, should scipy from pip (0.11.0) install
cleanly with numpy from pip (1.6.2)?

Thanks again,

Adam
