Stop downloading again, start unpacking. Fiddle fiddle, try the test...no dice.
Aha! Net::IRC! Off to CPAN, and after a very short download and installation (I should note here that the kindly T.J. Eckman pointed out the best way to handle Winstallation) I tested it and promptly worried that I had sent an unsupervised IRC bot out into the world.
I'm going to do another test. However, many of the perlbot plugins seem deadly useful, where the Engrishifier is -- let's face it -- a perhaps funny but utterly pointless thing.
