I've been following the BugZilla installation documentation and using mod_perl w/ apache2. Everything has gone fairly smooth and bugzilla pages appear to be getting rendered and served correctly, but I get some error message when restarting apache now, and a ton of errors showing up in the error log for the virtualhost every time a page is loaded.
This started happening after I added these two lines the docs say to add before any other mod_perl directives, so I placed it near the top of my httpd.conf.
PerlSwitches -w -T
PerlConfigRequire /var/www/bugzilla/mod_perl.pl
Now, when apache2 is restarted, I get this.
bugzilla01 ~: service apache2 restart
* Restarting web server apache2
