Python tb trying to run sugar

[Konstantin Ryabitsev]

Wanted to try running Sugar on my up-to-date F10 install, but it
crashes right away:

Traceback (most recent call last):
  File "/usr/bin/sugar-shell", line 30, in <module>
    from main import main
  File "/usr/share/sugar/shell/main.py", line 32, in <module>
    import view.Shell
  File "/usr/share/sugar/shell/view/Shell.py", line 38, in <module>
    from view.frame import frame
  File "/usr/share/sugar/shell/view/frame/frame.py", line 29, in <module>
    from view.frame.activitiestray import ActivitiesTray
  File "/usr/share/sugar/shell/view/frame/activitiestray.py", line 33,

    from model import shellmodel

    from model.devices.devicesmodel import DevicesModel
  File "/usr/share/sugar/shell/model/devices/devicesmodel.py", line
25, in <module>
    from model import network
  File "/usr/share/sugar/shell/model/network.py", line 23, in <module>
    from sugar import dispatch
ImportError: cannot import name dispatch

Installed via yum groupinstall "SUGAR Desktop Environment"

Anything obvious that I'm missing?
