Can't start 'gdesklets start'

gdesklets 0.36.3-2 on Fedora 15 (64 bit) using openbox WM.
When I type 'gdesklets start' into a terminal (without the quotes) I get this:
---------------------------------------------------------------
[daddy@F15b ~]$ gdesklets start
Traceback (most recent call last):
  File "/usr/bin/gdesklets", line 3, in <module>
    from main import client, DISPLAY, HOME, USERHOME

Maybe some Pthon package is missing?
