gl tool did not load: No module named Tk

Hi!

I am trying to run pizza.py on fedora 14 (gran_pizza_17Aug10 version) I am getting the following error when runing pizza.py with python 2.6

Loading tools ...
gl tool did not load:
No module named Tk

I used to get :
Loading tools ...
animate tool did not load:
No module named ImageTk
image tool did not load:
No module named Pmw
gl tool did not load:
No module named Tk

I tried "yun install python-imaging-Tk" and it fixed the first two but a module named Tk is still missing.

Please do HELP!!!

Thanks!!
