Hi, I am trying to install OTRS on a linux host: Red Hat Linux release 9 (Shrike); 2.4.20-8rlx4smp with Server version: Apache/2.0.48 and mod_perl-1.99_17 I am stopped at the README.webserver configuration. I added the following line to my httpd.conf: Include /ebi/www/main/includes/apache2-httpd.include.conf and have copied this file from $OTRSHOME/scripts/apache2-httpd.include.conf there. I have added the following line to this file in order to load mod_perl: LoadModule perl_module modules/mod_perl.so Then I run $APACHE_HOME/bin/apachectl configtest and it is OK but when I try to start httpd I get: [Fri Nov 26 18:18:47 2004] [error] Can't locate loadable object for module Apache::Constants in @INC (@INC contains: /ebi/www/main/otrs/Kernel/cpan-lib /ebi/www/main/otrs/ /ebi/www/common/perl/lib/5.8.2/i686-linux /ebi/www/common/perl/lib/5.8.2 /ebi/www/common/perl/lib/site_perl/5.8.2/i686-linux /ebi/www/common/perl/lib/site_perl/5.8.2 /ebi/www/common/perl/lib/site_perl . /ebi/www/common/apache/ /ebi/www/common/apache/lib/perl) at /ebi/www/common/perl/lib/site_perl/5.8.2/i686-linux/mod_perl.pm line 14 Compilation failed in require at /ebi/www/common/perl/lib/site_perl/5.8.2/i686-linux/Apache.pm line 6.
