Why would I need to define a new language, if the listing package 
documents the presence of printpod and podcomment variables?

That was my thought.

No, all the POD is within the Perl source.

Double quotes weren't a problem, just regular single quotes.  I 
don't know that setting printpod or podcomment would have fixed 
anything or not, all I know is that trying to set either generated 
errors.  I'm guessing the documentation is out of date with the 

I can completely understand the fact that Perl keywords are bold 
in the POD, as POD is legal Perl.  But LaTeX parsing doesn't seem 
to be up to what the Perl interpretter does.

Listings package can do.  A note to that effect is all that is 
needed.  But, manually adjusting the text looks reasonable enough
