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

[Attila Hammer]

Binary package hint: gnome-orca

Dear Ubuntu Developers,

I downloaded this morning the current Lucid daily live cd. I would like try choose the accessible profile with screen reader support.
The boot is completed correct, but Orca does'nt launched.

I open a gnome-terminal window, and try run following command:
orca -v

I see this error message when I run orca -v command (show the version number):
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.
