2d Sprite Engines for Perl
I personally would reccomend SDL. Even in C SDL is a great library to use, and while I haven't used it in Perl, looking through the module on CPAN it seems to be able to do everything I'd want to do in a typical SDL app.
As for useful tutorials and articles, I would reccomend learning SDL from the C perspective first from the SDL Tutorials then bringing that knowlege to Perl. At the very least give them a look over, as they have lots of useful tips and tricks scattered throughout.
