You need:

* D-Bus for Python (http://www.freedesktop.org/wiki/Software/dbus) 
 - almost every modern UNIX will have a package for this. You can install this in Debian/Ubuntu Linux by issuing:
 
   $ sudo apt-get install python-dbus

Restart the daemons:

$ dbus-send / org.apertium.General.QuitSignal
