A bug in JointTypeExample.py?

Hello,

I got an error running JointTypeExample.py in Mac OSX.
It seems like an easy to fix one, however: I was able to run the example just by swaping some arguments in the "self.joint.link" calls.
The methods signature are, e.g.
link( self, parentPoint, childPoint, childLink, parentLink, currentRotation )
while the calls in the example seem to use
link( self, childLink, parentLink, parentPoint, childPoint, currentRotation )

Here is the "Output log":
