Synaptic : Libglade for Python

[LinuxMurah.com]

here is my complete program taken from http://baypiggies.net/old/10mintig.html

#!/usr/bin/python

from gtk import *
from gnome.ui import *
from GDK import *
import libglade

def main():
 widgets = libglade.GladeXML('foo.glade')

 app1 = widgets.get_widget('app1')

 label1 = widgets.get_widget('label1')
 label2 = widgets.get_widget('label2')
 label3 = widgets.get_widget('label3')

 label1.set_text('New Label Text for Label 1');
 label2.set_text('New Label Text for Label 2');
 label3.set_text('New Label Text for Label 3');
 app1.set_title('This is a new application window title');

 mainloop()

if __name__ == '__main__':
 main()

when I run it in Ubuntu always error, so how I can change it so that
it can be run in Breezy? I have already 'glade-2' and 'python-glade2'
installed.
