The following have been tested on Mac OS X Yosemite (10.10) - earlier versions may not have a recent enough Python installation (recommended 2.7.6 or later).

$ echo 'import site; site.addsitedir("/usr/local/lib/python2.7/site-packages")' >> /Users/macmini/Library/Python/2.7/lib/python/site-packages/homebrew.pth</pre></li></ol>
