[mod_python] [SPAM] Problem installing on Apache 1.3.34/Win32 - "make_obcallback returned no obCallBack!"

Hello,

I've attempted to install mod_python on Apache 1.3.34 running on Windows XP 
Home.

I've downloaded and installed python-2.4.3.msi (with all default settings), 
extracted mod_python.dll from python2.2-apache1.3.22.zip to python's 
installation directory.

I've added the following to my httpd.conf:

  LoadModule   python_module "c:/python24/mod_python.dll"
  AddHandler python-program .py
  PythonHandler mptest
  PythonDebug on
  AddType text/html .py

Then I've copied python24.dll to python22.dll (leaping ahead: I've also 
tried installing Python-2.2.3.exe to get 'genuine' 2.2 DLL, but it didn't 
change anything). Apache starts OK telling:

  Apache/1.3.34 (Win32) mod_python/2.7.6 Python/2.2.3 PHP/4.4.2 running...

But when I try opening "Hello World" test file from my browser, I get Error 
500 and the following line in VirtualHost's error.log:

  [Sun May 28 16:17:39 2006] [error] [client 127.0.0.1] python_handler: 
make_obcallback returned no obCallBack!

Main error.log contains:

  'import site' failed; use -v for traceback
  make_obcallback(): could not import mod_python.apache.
  make_obcallback(): could not call init.

How can I fix it and make it work?

Thanks in advance,
Sanja

P.S. Please do not advise to upgrade to Apache 2 - it is not an option for 
me.
