[otrs] Once again :-) CentOS 4.x and OTRS :)

Hello! Dear friends, again several "stupid" problems with OTRS, used several ways to install 1. tried to use http://howtoforge.com/otrs_centos4.4 several troubles that we all knew already, but then just added repository ( in maillist were several comments ) and used : yum install otrs - it is ok. 2. but after I tried to restart http -> always error like this -> [Wed May 09 19:07:27 2007] [error] GATEWAY_INTERFACE not Perl! at /opt/otrs/scripts/apache2-perl-startup.pl line 5.\nCompilation failed in require at (eval 2) line 1.\n [Wed May 09 19:07:27 2007] [error] Can't load Perl file: /opt/otrs/scripts/apache2-perl-startup.pl for server XXXservernameXXX:80, exiting... Any ideas colleagues? VBrgs!
