[Zope] Zope import error

[Subramanian S]

Hi,
  I am trying to run the zope tests for APE, present in apelib/tests/ .
I get the following error:-
ERROR: test_btreefolder2 (__main__.PsycopgTests)
----------------------------------------------------------------------
Traceback (most recent call last):
  File 
"/var/opt/zope/default/Products/Ape/lib/apelib/tests/zope2testbase.py", line 
728, in test_btreefolder2
    from Products.BTreeFolder2.BTreeFolder2 import BTreeFolder2
ImportError: No module named BTreeFolder2.BTreeFolder2

Please help on how PYTHONPATH needs to be set for this.

Regards,
Subu
