As chromatic and others have written, there is a serious shortage of Perl programmers in London. The BBC (which does a lot of Perl) has even resorted to running free Perl training seminars. It may be similar in other parts of the world.
The thing is, Perl is just not "cool" anymore, so people not into the latest buzz won't pay it any attention. But there's still a lot of code from the original dot com boom days around which needs to be maintained. It may not last, but right now, it's definitely good to be a Perl programmer.
