Message215

When I include C:\Python2.0\Lib in the python.path registry entry on my WinNT machine, I get the following error on startup:

Jython 2.0alpha1 on java1.2.2 (JIT: symcjit)
Type "copyright", "credits" or "license" for more information.
error importing site
Traceback (innermost last):
  File "c:\Python20\Lib\site.py", line 206, in ?
AttributeError: class 'org.python.modules.os' has no attribute '__file__'

This error is in the site.py line:
here = os.path.dirname(os.__file__)

Without the Python20\Lib in python.path, jython executes, but of course can't import any modules such as rexec or xml that aren't included in jython\Lib.
