[SOLVED] Error restarting httpd after OTRS install

[tmoore82]

I'm trying to install OTRS Help Desk 3.3.2 on Cent OS 6.5 (Final). The initial installation (yum install) goes smoothly enough. The next step is to restart httpd, but the restart keeps failing. I don't get an error in the console, but when I check the error logs, I can see that it fails each time for the same reason:

I've tried adding /opt/otrs/scripts to @INC, but that doesn't seem to help.

**SOLUTION**

In the file /etc/httpd/conf.d/zzz_otrs.conf, there was an IfModule directive checking for "mod_perl.c." I changed this to look for "mod_perl.so," and the problem was solved.
