pyrocket crashes while starting

[prometheus]

When starting pyrocket, it crashes with the following error, no matter wheter I start the program as a normal user or as root:

-------------------------------------------------------------------------------
Traceback (most recent call last):
  File "/usr/bin/pyrocket", line 17, in <module>
    from rocket_frontend import RocketWindow
  File "/usr/lib/pymodules/python2.7/rocket_frontend.py", line 11, in <module>
    from rocket_webcam import VideoWindow
  File "/usr/lib/pymodules/python2.7/rocket_webcam.py", line 2, in <module>
    from opencv import cv, highgui
ImportError: No module named opencv
-------------------------------------------------------------------------------

I am working on a Ubuntu 12.04, all packages are up-to-date.

I would be glad if anymody could help me with the problem.

I get the same error message when attempting to run pyrocket on Ubuntu 12.04.
