In the process of installing Monarch, which is a Nagios file manager, earlier I ran into a couple errors for modules I thought I had already installed. Then I realized the issue must be because during the process of installing modules Perl wanted to upgrade from 5.8 to 5.10 on CentOS. I went ahead and upgraded Perl however I left 5.8.8 intact since CentOS seems to rely on Perl 5.8.8 in many ways. Anyhow the full error I received is below as noted from the Apache error logs. You can easily resolve the below error by following the directions below.
