While in no means is it a "scientific" search of Job sites or anything, by doing a quick search on Monster for perl jobs, I had no problem finding postings for them. I'll admit, using the same criteria for Java found more, but my point here is that it appears that there are plenty of perl jobs to be found. Is one of them exactly right for you? Couldn't answer that one, but would assume that if in the last 30 days there are over 1000 postings (Monster would only post to 1000) for anything in perl, I would be one of them is a match.
In the mean time, why don't you start playing around with the other languages (to include Java), you will probably find that making the switch from programming language x to programming languae y is a little easier than you think. IMHO, perl brings a whole bunch of the good things about other languages, while leaving most of the bad stuff behind. Because of this a lot of perl things are derived from other languages and while the syntax for perl maybe different that others, the concepts and ideas still translate over.
IMHO, I think that your fears are misplaced. It's a good thing that you are thinking about these things, though. It really sux to find your shorts around the ankles. No matter what you do, always prepare for the future. As robharper stated above here, "decided to learn some Perl last summer in order to add another string to my bow", it never hurts to expand your horizons.
Not a sermon, just a thought.
