<<~EOS
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
