It probably should check the version of Python at least. I'm a bit surprised 
by this error; the sqlite3 module was added to the Python standard library in 
2.5, and cadofactor.py requires Python 3 to run at all. Which versions of 
Python are installed? I.e., which (if any) do you get by executing "python 
-V", "python2 -V", and "python3 -V"?

Thanks,
Alex
