Your suggestion worked. But one error came up.

[ZODB3-3.4.0]# python test.py
Running tests from build/lib.linux-i686-2.3
Running unit tests:


Error in test testUmask (zdaemon.tests.testzdrun.ZDaemonTests)
Traceback (most recent call last):

   Ran 2173 tests with 1 failures and 1 errors in 160.065 seconds.

In the error message there is reference to 
/var/tmp/python2.3-2.3.5-root/usr/lib/python2.3/unittest.py.
But I have this: /usr/lib/python2.3/unittest.py
Do I have to modify something to remove that error?

Thanks for help, again.
Regards,
Nagaraj
