 Replying to [comment:14 nox at macports.org]:
 > The installation of a custom p5-test-harness in #13745 is unneeded,
 you're right. But it doesn't break anything.

 It currently breaks upgrades if the -f option isn't used.

 > If a core module file is omitted in your solution, we will need to force
 installation again,

 I suppose you mean an upgrade of the Perl core port.

 Yes, but there's a still problem for the binaries and man pages with this
 solution. The only workaround I can see is that the user would need to
 modify his $PATH environment variable in his shell rc file(s). But note
 that if you regard this modification as acceptable, then the user could
 also modify his $PERL5LIB environment variable at the same time, meaning
 that the reversed @INC path is completely unnecessary.

 > So if we create a new port for an updated core module, we'll have to
 increase the revision of perl base port and to remove the files of the
 core module from it. That's not elegant.

 I don't think there's any elegant solution.
