I regularly see Perl jobs posted in London, but the wages are surprisingly poor, compared to what I could get for my Django knowledge.

When you take that into account, the salary would need to be at a real premium to make it worthwhile, and the premium just isn't there.
I suspect there is too much else going on for a comparison of salaries by language to be meaningful. Those Perl programmers are probably highly paid mainly because they have 20ish years of experience, and lots of other valuable Linux/Unix experience. There are probably lots of fresh graduate and entry level JavaScript / Java / C++ developers bringing down those averages.
I always get a good laugh when I see job ads for a "Junior Perl developer" paying 25k GBP or something. They stopped making those 20 years ago.
