Hi Matt,
It is possible the module is installed but not loaded. You can check by
running one of the following commands:
RedHat/CentOS/Fedora: httpd -M
Debian/Ubuntu: source /etc/apache2/envvars && apache2 -M
You should see perl_module in the list returned. My general experience
is that Mod Perl is enabled automatically on RedHat-based Linux OS but
often you need to run "a2enmod perl" on Debian based systems. On RedHat
based systems there should be the file
/etc/httpd/conf.modules.d/02-perl.conf that loads Mod Perl. On
Debian-based systems there should be a symlinked file in
/etc/apache2/mods-enabled/ called perl.load that symlinks to
/etc/apache2/mods-available/perl.load.
Regards
David Newman
