In lucid, Orca does'nt found and import pyatspi module, but python-pyatspi package is installed

[Hammer Attila]

Dear list,

Possible this is early, but I would like try and testing current Lucid 
daily live cd.

When I choosed accessible profile with screen reader support, the boot 
is completed correct, the login sound I hear correct, but Orca does'nt 
launched.
I run orca -v command with gnome-terminal window, and see following 
error message:
Traceback (most recent call last):
   File "<string>", line 1, in <module>
   File "/usr/lib/pymodules/python2.6/orca/orca.py", line 54, in <module>
     import mouse_review
   File "/usr/lib/pymodules/python2.6/orca/mouse_review.py", line 28, in 
<module>
     import debug
   File "/usr/lib/pymodules/python2.6/orca/debug.py", line 32, in <module>
     import pyatspi
ImportError: No module named pyatspi

Why not found and import Orca the pyatspi module? python-pyatspy package 
are installed with the cd.

If this is help, I open a bugreport with this problem. The bug report 
link is following:
