Qualcuno sa cosa significa questo errore di Karamba quando avvio un'applet che si appoggia a script Python? Come lo posso risolvere?

codice:
[andrea@localhost ~]$ superkaramba Linuxnews/linuxnews.theme 
Could not find platform independent libraries <prefix>
Could not find platform dependent libraries <exec_prefix>
Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]
'import site' failed; use -v for traceback
superkaramba: TaskManager::TaskManager()
Traceback (most recent call last):
  File "/home/andrea/Linuxnews/linuxnews.py", line 2, in ?
    import time
ImportError: No module named time
------------------------------------------------------
What does ImportError mean?

It means that I couldn't load a python add-on for linuxnews.theme
If this is a regular theme and doesn't use python
extensions, then nothing is wrong.
