Perl did languish for a while.
Perl6 gave the language dabblers an opportunity to experiment with new ideas and concepts. Take the best of perl5, but not be afraid to be wildly incompatible, and see where it goes.
However, while all the cool kids were doing stuff in perl6, the perl5 folks realized they could do really cool things in perl5 too, right now. Perl5 now has Moose, Plack (Stolen from Ruby's Rack), new web frameworks to match and even better those of ruby, python, and even PHP. Perl5's maintainers started to actually chase down long standing bugs, and actually kill off the things that have been giving deprecation warnings in perl5. There's even a Perl Foundation grant out for someone doing full-time perl5 bug triage + fixing. (And if you've seen Perl5's source, you'll know that's no small feat)
My company's work in perl5 pays my bills. Perl5 is not going anywhere anytime soon, so I'm confident we can continue to move forward with it. Perl6, now that it's becoming more and more usable will inspire the imagination of developers, and continue to evolve, and the perl5 folks will continue to cherry pick the nifty features they can backport into perl5.
It's a very exciting future for perl all around, and I'm happy to be on board.
