Make sure you are loading the modperl DSO in your Apache configuration.

Something like this:

LoadModule perl_module modules/mod_perl.so

http://perl.apache.org/docs/2.0/devel/core/apache_integration.html#Enabling_the_mod_perl_Module_and_Installing_its_Callbacks

That said, RedHat (and other distributions for that matter) seem to 
always be behind in the versions of mod_perl that they ship. Since 
mod_perl is being constantly developed, you'd be better off getting the 
latest release from 
http://perl.apache.org/dist/mod_perl-2.0-current.tar.gz and building it 
yourself.

In order for Apache to test/load your Perl code on startup, you need to 
have startup file that loads all your (or other - e.g. CGI) modules, 
which you then tell Apache to execute when it starts up:

PerlRequire  /usr/local/apache2/conf/startup.pl

Check out:

http://perl.apache.org/docs/2.0/user/handlers/server.html#Startup_File
