I have a complete install of RH 8.0 (Psyche) on a PC with all packages. Mod_Perl is mod_perl-1.99_05-3, Apache is 2.0 and MySQL 3.23 I used the RPM installation for RH 8.0, and there were no errors during installation. To try and troubleshoot, I have looked at all files it lists as failing and the files exist and pass "perl -c FILENAME" with "Syntax OK". Also, I looked and the httpd.conf and all other apache-related .conf files are older time stamps (meaning no change from when Apache started successfully). I have pasted the error below, and I'm at a point where I don't know what to troubleshoot first/next. I have never gotten Mod_perl to work with Apache, since Apache is 2.0 and mod_perl is 1.x. I was told OTRS might work, however I'm not certain if I'm still hitting the same problems I hit when trying other perl-based tickting systems. I know this is off-topic, but can someone point me to a reference that describes downgrading RH 8's Apache from 2.0 to 1.3.23 (or similar). The error reads: httpd failed. The error was: Starting httpd: [Tue Oct 21 01:00:18 2003] [error] Can't locate loadable object for module Apache::Constants in @INC (@INC contains: /opt/otrs/Kernel/cpan-lib /opt/otrs/ /usr/lib/perl5/5.8.0/i386-linux-thread-multi /usr/lib/perl5/5.8.0 /usr/lib/perl5/site_perl/5.8.0/i386-linux-thread-multi /usr/lib/perl5/site_perl/5.8.0 /usr/lib/perl5/site_perl /usr/lib/perl5/vendor_perl/5.8.0/i386-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.0 /usr/lib/perl5/vendor_perl .) at /usr/lib/perl5/site_perl/5.8.0/i386-linux-thread-multi/mod_perl.pm line 14 Compilation failed in require at /usr/lib/perl5/site_perl/5.8.0/i386-linux-thread-multi/Apache.pm line 6.
