title: problems with python and virtualenvwrapper after updating: No module named virtualenvwrapper
body: <p>I run python 2.7.6 with virtualenv, virtualenvwrapper under ubuntu 14.04.
  now i have installed python 2.7.9 from source. the new python interpreter is now located under <code>/usr/local/bin</code> but it seems the old interpreter is also located under <code>/usr/bin</code>.</p>
  
  <p>if I run python shell it shows up python2.7.9. but if I use <code>mkvirtualenv venv</code> I am getting the following message.</p>
  
  <blockquote>
    <p>New python executable in venv/bin/python<br>
    Installing setuptools, pip...done.<br>
    Blockquote /usr/local/bin/python: No module named virtualenvwrapper</p>
  </blockquote>
  
  <p>old <code>.bashrc</code> (with working configuration using python 2.7.6 interpreter)</p>
  
  <pre><code># virtualenv-wrappper path
  export WORKON_HOME=$HOME/.virtualenvs
  export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python
  export VIRTUALENVWRAPPER_VIRTUALENV=/usr/local/bin/virtualenv
  source /usr/local/bin/virtualenvwrapper.sh
  </code></pre>
  
  <p>new <code>.bashrc</code> (with failure configuration)</p>
  
  <pre><code># virtualenv-wrappper path
  export WORKON_HOME=$HOME/.virtualenvs
  export VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python
  export VIRTUALENVWRAPPER_VIRTUALENV=/usr/local/bin/virtualenv
  source /usr/local/bin/virtualenvwrapper.sh
  </code></pre>
  
  <p>with the new <code>.baschrc</code> I type in <code>source .bashrc</code> and get the following output.</p>
  
  <blockquote>
    <p>/usr/local/bin/python: No module named virtualenvwrapper
        virtualenvwrapper.sh: There was a problem running the initialization hooks.</p>
    
    <p>If Python could not import the module virtualenvwrapper.hook_loader,
        check that virtualenvwrapper has been installed for
        VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python and that PATH is
        set properly.</p>
  </blockquote>
  
  <p>And I have also tried <code>which -a python</code>:</p>
  
  <p><strong>output:</strong></p>
  
  <pre><code>/usr/local/bin/python
  /usr/bin/python
  </code></pre>
  
  <p>I want to use python 2.7.9 with virtualenv and virtualenvwrapper. so what I have to do to get this running ?</p>
