Python Error, help

[Rod Person]

I'm trying to teach myself python. I installed py-ui package and I'm trying to 
run this example script:

import pyui

def onPress(button):
    print "the button was pressed"

pyui.init(320,320,"gl")

newFrame = pyui.widgets.Frame(10, 10, 200, 200, "hello world!")
newFrame.setLayout(pyui.layouts.GridLayoutManager(3,3))

for i in range(0,9):
    button = pyui.widgets.Button("button #%s" % i, onPress)
    newFrame.addChild(button)
    
newFrame.pack()
pyui.run()
pyui.quit()


I get the following Error:
 No module named WGL__
