That's not correct:
------------------------------ [ BEGIN Head of 
aclock.py ] ------------------------------
#!/usr/bin/env python

import sys
import qtui
from qt import *

   return x
class AnalogClock(QWidget):
------------------------------ [ END   Head of 
aclock.py ] ------------------------------

I commented in/out "import qtui"
