title: Pygame Import Error: cannot import name _camera
body: <p>I'm using the camera.py file from the examples folder supplied with pygame.</p>
  
  <p>Unfortunately, every time I try to run camera.py, it shows this error message:</p>
  
  <pre><code>Traceback (most recent call last):
    File "camera.py", line 92, in &lt;module&gt;
      main()
    File "camera.py", line 87, in main
      pygame.camera.init()
    File "/usr/local/lib/python3.3/site-packages/pygame/camera.py", line 42, in init
      from pygame import _camera
  ImportError: cannot import name _camera
  </code></pre>
  
  <p>I'm assuming that this means _camera.py is missing, though I'm not too sure.
  Any help?</p>
