G'day hurricup,

That's part of the constructor (new()) code. From the Net::NNTP documentation, you can provide "... an array with hosts to try in turn.".

Changing last: to last; will stop it trying after the first success (which is probably the intent).

I'll take your word for it, that there's no label called 'last' referenced elsewhere in the code. I was trying to think of way you could actually do that without generating an error (e.g. 'next last;', 'last last;', etc.); however, Perl seems to handle it OK:

$ perl -MO=Deparse -e 'next last;'
next (last);
-e syntax OK
[download]

$ perl -MO=Deparse -e 'last last;'
last (last);
-e syntax OK
[download]

Looks like you're going to be spending a fair bit of time on rt.cpan.org today. :-)
