Hmm, that post sounds like it might have come from someone who had been in attendance at the Thousand Oaks Perl Mongers meeting a couple nights ago. The Perl Debugger was one of the topics. And I myself have finally vowed to become more comfortable with it.

Or you may just already be a believer, and kudos for that.

To that end, there is perldebtut and perldebug. I would probably take them in that order. The topic is also covered in the Camel book, and the Alpaca book.
