which I guess means we want an implementation of the Camel book 2nd edition
(`Programming Perl'), as Perl 5 is not a standard.  And my understanding is
that our code is legal by the Camel book, but 5.003 mis-parses it.

Thanks for the confirmation.

Would people notice a warning in all the output from configure?  This has
come up twice in the last year and a few more times before (with RedHat 5.2
as I recall).  We know that 5.003 is the one that caused the last two, so I
do think

${PERL} -e 'require 5.004 or exit 1'

would be a good idea.
