[otrs] Facing Problem with perlrequire

Hi, I have installed OTRS 2.1.3 on SuSE Linux Server 10.0 After installation, when I want to start http service, I am getting the following error. I have required modules under /etc/sysconfig/apache2 file. This didn't resolve the problem. Syntax error on line 10 of /etc/apache2/conf.d/otrs.conf: Invalid command 'PerlRequire', perhaps misspelled or defined by a module not included in the server configuration I am looking for help from some one who has overcome this problem. Regards, Prafulla Kumar
