title: I installed PyOpenGl for python3, and when I import packages I get value errors
body: <p>I wanted to start with some PyOpenGL, and so I booted into Mac Osx to try it. I went on the PyOpenGl website, downloaded the PyOpenGl and PyOpenGl_accelerate tars, cd'd into my downloads directory, and typed these commands into terminal to install:</p>
  
  <pre><code>tar -zxvf PyOpenGL-3.0.2.tar.gz
  cd PyOpenGL-3.0.2
  python3 setup.py install #I changed 'python' to 'python3' to install it to my python3. 
  </code></pre>
  
  <p>next, i typed these to install the accelerate package</p>
  
  <pre><code>tar -zxvf PyOpenGL-accelerate-3.0.2.tar.gz
  cd PyOpenGL-accelerate-3.0.2
  python3 setup.py install #Again, 'python' replaced with 'python3'
  </code></pre>
  
  <p>Finally, I ran this code to test the install</p>
  
  <pre><code>python3
  &gt;&gt;&gt;from OpenGL.GL import *
  </code></pre>
  
  <p>which gave me this lovely string of errors</p>

  <p>Any idea why it's acting up like this?</p>
  
  <p>EDIT: managed to get pyopengl working for python3 with following command:</p>
  
  <pre><code>sudo pip-3.3 install PyOpenGL
  </code></pre>
  
  <p>So... problem solved I guess...</p>
