py2exe prob

[ryan]

my program uses unicode functions and so i compile like:
"python setup.py py2exe --packages encodings"

which seems to create unicodedata.pyd and zlib.pyd, the problem is when i
run my exe it acts like it didnt do that, it still gives me the error:

ImportError: No module named warnings
warning: assignment shadows builtin
Traceback (most recent call last):
  File "<string>", line 110, in ?
  File "<string>", line 82, in main
  File "handle_keyboard.pyc", line 113, in handle_keyboard
  File "open_url.pyc", line 126, in open_url
  File "input_box.pyc", line 53, in ask
  File "input_box.pyc", line 21, in get_key
LookupError: no codec search functions registered: can't find encoding

also at the top of the error it said:
ImportError: No module named warnings
warning: assignment shadows builtin

anyone know how to fix this or at least what it means?
