I like this.

And +1 to Mojca's proposal to drop the revision number or possibly the perl port group epoch bump.

My current version of perl5.12 is 5.12.5:
$ port -q installed perl5.12
  perl5.12 @5.12.5_0 (active)

I just uninstalled and reinstalled p5.12-digest-crc:
$ port provides /opt/local/lib/perl5/vendor_perl/5.12.4/darwin-thread-multi-2level/Digest/CRC.pm 
/opt/local/lib/perl5/vendor_perl/5.12.4/darwin-thread-multi-2level/Digest/CRC.pm is provided by: p5.12-digest-crc

The files installed by p5.12-digest-crc came from the packages.macports.org:
http://packages.macports.org/p5-digest-crc/

So to keep the placement of p5.12 modules unified I must force upgrade from source "-s" after each perl 5.12 version update.
