Creating Vertex Array Object

I’m trying to create a vertex array object on Mac OS 10.9 (using PyOpenGL 3.0.2)
and running into a NullFunctionError.  They’re definitely supported: OpenGL
Extension Viewer says core features up to 4.1 are implemented, and VAOs were
introduced in 3.0.

Here’s a 6-line example that reproduces the issue:

from OpenGL.GL import *
from OpenGL.GLUT import *

glutInit()
glutCreateWindow("GL test")

print glGenBuffers(1)
print glGenVertexArrays(1)

which fails with the exception
OpenGL.error.NullFunctionError: Attempt to call an undefined function glGenVertexArrays, check for bool(glGenVertexArrays) before calling

Can anyone familiar with function construction help me track this down?

Thanks,
Matt
