Google, Facebook, Twitter authentication on Perl

Hello, need working scripts, that will allow use Google, Facebook, Twitter authentication. You may use any modules from CPAN (but modules must be not outdated and supported). I need 3 scripts (for each social network): each script have LOGIN button and after authentication they must return authentication information. Doesn't need any databases or something, I will implement this myself. I will pay only after testing and you need send me one of three scripts, that I may inspect code. Thank you.
