title: Error with PyOpenGL and glutSolidCylinder
body: <p>I'm attempting to draw a solid cylinder using PyOpenGL (along with PyODE), however I am met with the following error:</p>
  
  <pre><code>OpenGL.error.NullFunctionError: Attempt to call an undefined function glutSolidCylinder, check for bool(glutSolidCylinder) before calling
  </code></pre>
  
  <p>I have the following three imports, and have been using other glut* calls (glutSolidSphere, glutSolidCube, etc) with no issue, but this one causes me problems.</p>
  
  <pre><code>from OpenGL.GL import *
  from OpenGL.GLU import *
  from OpenGL.GLUT import *
  ...
  glutSolidCylinder(RADIUS, LENGTH, SLICES, STACKS)
  </code></pre>
  
  <p>I'm using Python  2.7, and when I test with <code>print(bool(glutSolidCylinder))</code> I receive <code>False</code>.  </p>
  
  <p>I'd used Pip to install PyOpenGL as well.</p>
