title: how do I update PYTHONPATH from /usr/local/bin/python to /usr/bin/python
body: <p>I am unable to use virt-manager, and I think it's because of where my python is located.  When I run the <code>virt-manager</code> command I get: <code>No module named libvirt</code> even though I have libvirt installed.  When I run <code>/usr/bin/python /usr/share/virt-manager/virt-manager.py</code> it works fine.  The output from <code>which python</code> is <code>/usr/local/bin/python</code>.  I've tried creating a <code>~/.bash_profile</code> that contains this: <code>export PYTHONPATH=$PYTHONPATH:/usr/bin/python</code> but am still having the same problem.
  I'm sure there is a simple solution to this?</p>
