I'm trying to run test-kernel-security.py from this Ubuntu wiki page, but when I try to run it I get the following error:

Code:
alex@kubuntu:~$ python test-kernel-security.py
Traceback (most recent call last):
  File "test-kernel-security.py", line 49, in <module>
    import testlib
ImportError: No module named testlib
How do I add this module?
