The perl PATH here doesn't include /usr/local/nagios/libexec so utils.pm can't be located.

The person who wrote the plugin apparently did so on a system where the plugins had been installed via third party or distribution specific package (hence the /usr/lib/nagios/plugins path). Edit the script and change 

use lib "/usr/lib/nagios/plugins";

to

use lib "/usr/local/nagios/libexec";
