This seems to be correct.

use YYY;
use lib '${prefix}/lib/perl5/vendor_perl/';
use YYY VERSION;
@INC = @lib::ORIG_INC;

results in an error if VERSION is the newer version.
In runs fine, however, if the first "use YYY" is commented out.

I was hoping to avoid modifying @INC.
It seemed that ${prefix}/bin/perl should not behave differently depending
on which p5 ports are installed.
I am out of ideas on how to make that happen however.

How about this:
   * Modify @INC so the newer p5 ports are found first.
   * Do not add conflicting p5 port as dependencies unless the newer version is
          actually required (mitigate the potential problems).
   * Prepend p5- to the conflicting man pages.
