You can tell if it really worked by looking in the server's error log
right after you restart the server. On my FreeBSD system I get:

# /opt/www/bin/apachectl restart
/opt/www/bin/apachectl restart: httpd restarted 
# tail /opt/www/logs/error_log
[Tue Aug 28 06:37:46 2001] [notice] SIGHUP received.  Attempting to restart
[Tue Aug 28 06:37:46 2001] [notice] Apache/1.3.19 (Unix) mod_loopback/1.2
    PHP/4.0.4pl1 mod_python/2.7.5 Python/2.0 configured -- resuming normal

If you don't see the mod_python entry then the DSO isn't registered.

Make sure the lines:

LoadModule python_module     libexec/mod_python.so
AddModule mod_python.c

are in your configuration file.

OK, so it sounds like the DSO is loading OK. Is the mod_python package
in your Python interpreter's load path? Do you have more than one copy
of Python on the machine? In the past I've had problems in that

Can you send the precise errors reported in the error_log and, if
applicable, in your messages file?

FWIW, I make use of mod_python in both <Directory> and <Location>
directives, using both SetHandler and AddHandler.

Ugh, anything but that. :-)

Sorry I can't offer more right now.
