title: Installing python3 in Linux when python2 is native
body: <p>I'm trying to get python3 working and all setup while keeping the python2 libraries in tact (system dependencies and all that).</p>
  
  <p>I've installed Python3.3 (compiled, etc..) and its in /usr/bin/Python3 side by side with /usr/bin/Python2.x</p>
  
  <p>Entering 'python' will take me to a 2.6 IDE and 'python3' or 'python3.3' does nothing. I'm just a little confused, I'm not sure why this isn't working at the moment.</p>
  
  <p>I can actually call it with /usr/bin/python3/bin/python3 and it works. This doesn't look too pretty though, what should I do here?</p>
  
  <pre><code>$ pwd
  /usr/bin/python3/bin
  
  
  $ ls
  2to3      idle3.3   python3           python3.3m         pyvenv
  2to3-3.3  pydoc3    python3.3         python3.3m-config  pyvenv-3.3
  idle3     pydoc3.3  python3.3-config  python3-config
  
  
  
  $ cat /proc/version
