Ubuntu :: IMac G5 Jockey-gtk Won't Start

I installed the ppc version of ubuntu 10.10 on my moms iMac g5 and cannot open additional drivers aka jockey-gtk. I simply see the "searching for additional drivers" window appear for just a sec, than nothing else.

in terminal I get a list of stuff i'm assuming are errors. So far none of the other solutions on the forum have worked that have solved it for other people.
here is what it gives me when I try to run in terminal:

Code:
leslie@leslie-desktop:~$ jockey-gtk
Exception in thread thread_call_progress_dialog:
Traceback (most recent call last):
File "/usr/lib/python2.6/threading.py", line 532, in __bootstrap_inner

[Code]....
