[PythonCAD] ImportError: No module named pygtk

[Wilbert Knol]

Revision 2769 produces this error:

wk at wk:~/pythoncad$ ./gtkpycad.py
Traceback (most recent call last):
  File "./gtkpycad.py", line 30, in ?
    import pygtk
ImportError: No module named pygtk
wk at wk:~/pythoncad$     

To me, it looks like a pythoncad-only library module:

wk at wk:~/pythoncad$ find ./ -iname pygtk
wk at wk:~/pythoncad$ 

I am lost.

Wilbert.
