(In my google-ing experience). Any ideas would be appreciated

In order to use most CPAN module effectively you should learn the basics first. Get some book book for learning Perl and follow it.

Google is a good tool for solving very specific problems, but not for learning the basics. Programming without actually understanding what you are doing and why, just copy&pasting code from here and there, and then trying to get the result to work would only produce one output: pain!
