title: Python, Install Beautiful Soup4-4.1.3 on Mac. Access Denied?
body: <p>I can't figure out how to install BeautifulSoup4 on Python.
  I've downloaded it, unpacked it and moved it to User directory.
  Typed in Terminal 'cd beautifulsoup4-4.1.3' to enter directory
  Then I type 'python setup.py install'
  Then I get this message:</p>
