RT 3.6 apache start error: Can't locate Apache2.pm in @INC


I am installing RT 3.6 on fedora core 5 and having some problems starting Apache 2. Following the FedoraCore4InstallationGuide I added the following VirtualHost section to the httpd.conf:

ServerName your.rt.server.hostname
DocumentRoot /opt/rt3/share/html
AddDefaultCharset UTF-8

this line applies to Apache2+mod_perl2 only

PerlModule Apache2 Apache::compat

PerlModule Apache::DBI
PerlRequire /opt/rt3/bin/webmux.pl

SetHandler perl-script PerlHandler RT::Mason

but after this apache fails to start, giving the error: Can’t locate Apache2.pm in @INC
I am not expert at all in configuring Apache and the mod_perl, anyone can help me with this issue?
Thank you,
