Umm, no, you are right, I was too fast when doing this today. sorry for noise.

Well, I have used the apache.import functions as Graham proposed yesterday. The code
looks like this at the moment in file where I import my own modules and works:

#! /usr/bin/env python

# $Id:

# import system-wide modules as they are in the PYTHON_PATH
import os

# import our modules but do not depend on PYTHON_PATH
# When we get executed under mod_python, the cuurent
# directory is not in PYTHON_PATH _if_ PythonHandler
# was not defined under "Directory" directive in httpd.conf
# or within .htaccess. But that still doesn't help
# with modules located in subdirectories - those are
# not in PYTHON_PATH even in "Directory" case!
# So, workaround that too here.

    from mod_python import apache

    _directory = os.path.dirname(__file__)
    for _my_modulename in ['web_settings', 'web_header', 'web_menu', 'web_text_frame', 'web_footer', 'sql_io', 'helper_functions']:
        __dict__[_my_modulename] = apache.import_module(_my_modulename, path=[_directory])
    import web_settings
    import web_header
    import web_menu
    import web_text_frame
    import web_footer
    import sql_io
    import helper_functions
