Since I've done a little something along those lines, try the following:

• Crank up the warnings in your httpd.conf file. I like to see some action in the error and access logs. You should at least be able to see the page being requested in the access log.
• Try telnetting into port 80 to see if you are getting anything.
• Try running the scripts from the command line. You may have to su to apache to get this to work.

Good luck.
