Aha!  I wondered if it was a Perl version thing.  I'll fix this, thanks!

What I'm thinking is to have the daemon write its PID to a file in the work
directory.  Then hashcash-sendmail can check whether there's one running
that way.  That has a couple of problems, and I haven't done it yet.  I'm
wondering if there's a better way...something that'll make it all "just
work."

What do you suggest?  I'm basically taking my cue from SpamAssassin, which
recognizes 26 bits as being worth a -5 to the spam score.
