I wouldn't really say that perl programmers are necesarrily a dying breed, but they might be harder to find in the midst of all of the mainstream programming out there (java, c++, c#, etc.). Granted I've only been really getting into the perl community for the past 6 months or so. To me, it seems like there will always be perl programmers and a need for them. There will also always be people curious about perl and people that just go out and learn it on their own.
I think that these forums pretty much speak for themselves and show that perl programmers aren't a dying breed.
