I’ve had a very brief stab, and it seems to be expecting a GUI/X (for zenity) or at least for the menu options anyway.
It looks like this is core to it:

But when I try to run it manually I get syntax errors. So not sure if it likes the Wheezy distribution or not really. I dont know enough about linux to do much more unless I try again in X.
