Looks as if a Python 2.1.x tries to execute Python 2.2 code.


Usually, Python protects itself against such incidents.
You might have a buggy PYTHONPATH in your environment.

It was introduced in Python 2.2.

You will in the "Python Language Reference" -- for Python 2.2 or higher.

You must determine why a Python 2.1.x happens to use "types.py"
from a Python 2.2 installation.


When you are ready to regenerate Zope (this is easy),
you can regenerate it to use Python 2.2 and forget
Python 2.1.
