Opengl Constant problem

Hi! I'm new to OpenGL and PyOpenGL, but Im trying to create a project to my
colledge and I'm facing a big problem. I was trying to resolve it but
without luck :(

I'm trying to execute the python example (volume rendering in pyopengl)
from http://www.siafoo.net/snippet/310, which uses the code from
http://www.siafoo.net/snippet/142 and in that code the author uses PyOpenGL
constant GL_STATIC_DRAW_ARB.

Unfortunatelly my Python (2.7) with PyOpengl 3.0.2-r1000 complains, that
this variable is not defined (gentoo linux, x86 64).

It is used though in some examples like:
http://www.songho.ca/opengl/gl_vbo.html.

So the api has changed? Or maybe the example is wrong?

How can I use glBufferData from OpenGl and what to pass as fourth argument
to make it working?

In the example there was glBufferData(GL_ARRAY_BUFFER, data[i],
GL_STATIC_DRAW_ARB), where data is numpy array containing volume
representation of an object.

I would be very thankful for any help!

All the best,
Wojtek
