title: Vim python-mode plugin picks up system python and not anaconda
body: <p>When i use python-mode it uses my system (mac python), I have anaconda installed and want Vim to autocomplete etc with that version of python</p>
  
  <p>As it stands now, python-mode will only autocomplete modules in from system python and not any other modules e.g. pandas that is installed in the anaconda distro.</p>
  
  <p>thanx
  Tobie</p>
