I don't think it comes installed on SME. You will need to either make, or look around for, a rpm of that Perl module. Have a look at rpmfind.net I'm pretty sure you will find what you want there.
After you install the module, put the script in the cgi-bin directory of an ibay, or primary web site, (make sure that you have cgi's enabled in the server-manager for the respective ibay) and then follow the install directions with the script. I've installed it before and it worked fine.
