Weird issue with python six: cannot import urllib
<p><a href="https://github.com/getsentry/raven-python" rel="nofollow">raven</a> ships with its own version of the <a href="https://bitbucket.org/gutworth/six/" rel="nofollow">six</a> module which seems to prevent me from importing a module which exists in the standalone six module. Please see below:</p>

[GCC 4.8.2] on linux2

&gt;&gt;&gt; 
&gt;&gt;&gt; 
&gt;&gt;&gt; from raven.utils import six       
&gt;&gt;&gt; dir(six.moves)
['__doc__', '__name__']
&gt;&gt;&gt; 
&gt;&gt;&gt; 
&gt;&gt;&gt; import six
&gt;&gt;&gt; six.__version__
'1.9.0'
&gt;&gt;&gt; 
&gt;&gt;&gt; 
&gt;&gt;&gt; 
&gt;&gt;&gt; dir(six.moves)
['BaseHTTPServer', 'CGIHTTPServer', 'SimpleHTTPServer', 'StringIO', 'UserDict', 'UserList', 'UserString', '__doc__', '__name__', '_dummy_thread', '_thread', 'builtins', 'cPickle', 'cStringIO', 'configparser', 'copyreg', 'dbm_gnu', 'email_mime_base', 'email_mime_multipart', 'email_mime_nonmultipart', 'email_mime_text', 'filter', 'filterfalse', 'html_entities', 'html_parser', 'http_client', 'http_cookiejar', 'http_cookies', 'input', 'intern', 'map', 'queue', 'range', 'reduce', 'reload_module', 'reprlib', 'shlex_quote', 'socketserver', 'tkinter', 'tkinter_colorchooser', 'tkinter_commondialog', 'tkinter_constants', 'tkinter_dialog', 'tkinter_dnd', 'tkinter_filedialog', 'tkinter_font', 'tkinter_messagebox', 'tkinter_scrolledtext', 'tkinter_simpledialog', 'tkinter_tix', 'tkinter_tkfiledialog', 'tkinter_tksimpledialog', 'tkinter_ttk', 'urllib', 'urllib_error', 'urllib_parse', 'urllib_robotparser', 'winreg', 'xmlrpc_client', 'xmlrpc_server', 'xrange', 'zip', 'zip_longest']

&gt;&gt;&gt; 
&gt;&gt;&gt; 
&gt;&gt;&gt; 
&gt;&gt;&gt; import six.moves.urllib
Traceback (most recent call last):
  File "&lt;stdin&gt;", line 1, in &lt;module&gt;
ImportError: No module named urllib

<p>To reproduce this, install <code>requests==0.14.1</code> in your virtual environment along with <code>moto</code> and <code>raven</code> and run the following script:</p>

<pre><code>from raven.utils import six as six1
from moto import mock_s3
</code></pre>

<p>Any hints would be appreciated. </p>
