title: Python httplib2 AttributeError: 'builtin_function_or_method' object has no attribute 'new'
body: <p>I am trying to scrape text from wikipedia. Since httplib2 is already installed, I thought I would use it.</p>
  
  <p>When I go through the simple retrieval from their <a href="http://code.google.com/p/httplib2/wiki/Examples" rel="nofollow">basic examples</a>, the first example gives me this error.</p>
  
  <pre><code>&gt; import httplib2
  &gt; h = httplib2.Http(".cache")
  &gt; url = "http://code.google.com/p/httplib2/"
  &gt; h.request(url, "GET")
  
  Traceback (most recent call last):

  <p>I'm running on Mac OS X, Python Version: 7.2-2 (64-bit), Enthought Distribution.</p>
  
  <p>I'm thinking it might be an issue with a faulty installation, but then again httplib2 came installed with other packages that I've been using. Also, I could try to reinstall httplib2, but I'm hesitant to do that, thinking it might break other things that are currently working.</p>
