Apache 2.2.3 not starting, just upgraded to mod

ARiccela has asked for the wisdom of the Perl Monks concerning the following question:

Still trying to get this rebuilt Red Hat Linux box to fly, it's getting off the ground but not staying in the air. I'm not sure if this is a problem with Apache or with mod_perl2. If it's not a Perl problem, I apologize, but if someone could point me in the right direction I'd appreciate it. We re-installed libwww-perl and mod_perl2 bundles via CPAN and Apache 2.2.3 server. We tried to start Apache and got the following error:

#apachectl start
apachectl: Configuration syntax error, will not run "start":
Syntax error on line 610 of /etc/httpd/conf/httpd.conf:
Invalid command 'PerlModule', perhaps misspelled or defined by a modul
+e not included in the server configuration
[download]

So we go to line 610 in httpd.conf and find the code block below. We can start Apache *if* we comment out this entire section, but then some of our custom-written Perl modules don't seem to work:

Alias /perl/ /cgi-bin/
    PerlModule Apache::Registry
    <Location /perl>
        SetHandler perl-script
        PerlHandler Apache::Registry
        #PerlOptions +ParseHeaders
        Options ExecCGI FollowSymLinks
        #Order allow,deny
        Allow from all
        #AllowOverride All
        PerlSendHeader On
    </Location>
[download]

OK, so some digging/research shows changes we didn't know we had to make to httpd.conf:

PerlModule ModPerl::Registry 
Alias /perl/ /home/httpd/perl/ 
    <Location /perl>
     PerlHandler ModPerl::Registry
...
[download]

So we made the changes, still getting the same error. So then we commented out everything between the Location tags, thinking there might be some syntax error in there causing problems. Nothing changed. Our limited experience at this point has us asking for help on this as we're not sure what to check out next.

So, uh, if these libs weren't, uh, presently found in any directory, that would probably be why we're having problems...? Would this be a problem of a bad mod_perl2 install or an incorrect RH config? I'm assuming RH but I'd like confirmation on that. Thanks!	[reply]

You either don't have mod_perl installed or aren't loading the module. Can you tell us how you installed mod_perl and apache?	[reply]

The solution to the problem was twofold - CGI.pm wasn't installed(!), which I could have sworn was installed, and the aforementioned change to httpd.conf was needed as well. Now Apache starts and our website can be seen. Now the db can't be hit... more fun! Thank you to all who helped!	[reply]

@Perrin - mod_perl2 was installed by me via CPAN shell. Apache 2.2.3 was installed by SA setting up RH box. I do not know exactly what he did, and this person isn't exactly forthcoming with answers when I ask questions. @AnonMonk - I have just found that site, have begun to dig through, thank you for the lead.
