Sheldon Hearn e19aceb0b2 * Drop deprecated USE_PERL5.
* Move the contents of pkg-message into POST-INSTALL-NOTES, which
  gets installed in the !NOPORTDOCS case for future reference.

* Refer to POST-INSTALL-NOTES from pkg-message in the !NOPORTDOCS
  case.  In the NOPORTDOCS case, use POST-INSTALL-NOTES as the
  pkg-message.
