[Visualpython-users] Mac OSX 10.4 PPC install issues

I am thinking of using vpython with a short python course where I am
restricted to using iBook G4 laptops with OSX 10.4 installed.
I have installed python 2.6.4 and the vpython listed on the vpython
site that appears to be appropriate (ostensibly for OSX 10.4 or
later):

VPython-MacPPC-Py2.6-5.12 (older 5.12 for PowerPC Mac)

However, attempts to use vpython meet with the error shown below. Is
there a workaround for this or am I just plain out of luck?
