title: installing modules into python2.7 when using multiple versions
body: <p>I have been using python2.6.  I needed to update to python2.7, so I installed it, and now I have both versions of python installed.  I need to know how to install modules like django in python2.7.  I have django installed already for 2.6, but when I try and run python.manage.py on 2.7 I get this error:</p>
  
  <pre><code>Traceback (most recent call last):
  File "manage.py", line 8, in &lt;module&gt;
      from django.core.management import execute_from_command_line
  ImportError: No module named django.core.management
  </code></pre>
  
  <p>I am using Ubuntu 10.04, and I have read on this site that it uses python2.6 by default and it is not a good idea to remove it because the os uses it for certain things.  When I try and re-install django it says the requirement is already met by python2.6.  Thanks for any help.</p>
