title: Python ImportError: cannot import name __version__
body: <p>I'm trying to use requests and requests_oauthlib, and right now am just trying the dead simple Twitter verify credentials example they use in the documentation for requests_oauthlib to confirm I've got the basics working. I did a "pip install requests requests_oauthlib" to get the modules. In a terminal window I can "import requests" no problem but when I try "import requests_oauthlib" I get this:</p>
  
  <pre><code>&gt;&gt;&gt; import requests_oauthlib
  Traceback (most recent call last):
    File "&lt;stdin&gt;", line 1, in &lt;module&gt;
    File "/usr/lib/python2.7/site-packages/requests_oauthlib/__init__.py", line 1, in
    &lt;module&gt;
      from .oauth1_auth import OAuth1
    File "/usr/lib/python2.7/site-packages/requests_oauthlib/oauth1_auth.py", line 10, in  
    &lt;module&gt;
      from requests.utils import to_native_string
    File "/usr/lib/python2.7/site-packages/requests/utils.py", line 23, in &lt;module&gt;
      from . import __version__
  ImportError: cannot import name __version__
  </code></pre>
  
  <p>Line 23 of utils.py does indeed look like this:</p>
  
  <pre><code>from . import __version__
  </code></pre>
  
  <p>I'm using Python 2.7.5 on Fedora and am currently banging my head against this wall after multiple tries at getting it working, any help would be greatly appreciated...</p>
