[otrs] Problems with installing OTRS from rpm...Please help!

Hi all, I am trying to install OTRS on a RedHat 9 box that has all other components (Apache, MySQL ) installed from rpm. I am using the RedHat 8.0 rpm. Installation was fine. but when I tried to restart apache with service apache restart I got the following error: Starting httpd: Syntax error on line 10 of /etc/httpd/conf.d/otrs.conf: Invalid command 'Perlrequire', perhaps mis-spelled or defined by a module not included in the server configuration I don't have mod-perl installed..is installing mod-perl a requirement? I would prefer to avoid having to install it. Many thanks for the help!
