If you use system python (that comes - depending on the OS X version -
|

with older versions of numpy, scipy and matplotlib), you may need to
|
|
ensure that the brewed packages come earlier in Python's sys.path with:
|
|
mkdir -p #{user_site_packages}
|

echo 'import sys; sys.path.insert(1, "#{homebrew_site_packages}")' >> #{user_site_packages}/homebrew.pth
