[twill] problem installing and running twill (total newbie, obviously)

[Big Daddy]

I get the following error when I try to run twill-sh:

Traceback (most recent call last):
  File "C:\Python25\Scripts\twill-sh-script.py", line 8, in <module>
    load_entry_point('twill==0.8.5', 'console_scripts', 'twill-sh')()

    self.basic_gt = mechanize.pp_get_title
AttributeError: 'module' object has no attribute 'pp_get_title'

What am I doing wrong?
