As long as perl is useful to and educational for you, who cares what someone else says about the popularity of the language you use? Seriously, since I joined this site, I have seen various threads of people bemoaning this same thing-that this report claims perl's demise, that that survey or index reports that perl is dead or on its way out. Saddening, maddening, yes. But really, why should they matter? Perl will continue for as long as it is useful or someone finds value in its use. If you are worried about your skill sets, then by all means try to pick up another language (or two, or more, if the urge hits you), and take to heart what each of them teaches you, but I would not sweat it too much just yet.
