 This does not make sense. How can it use the system Perl to run but load a
 Perl module provided by MacPorts?

 It’s MacPorts policy for ports that require Perl or a Perl module to
 depend on a specific version of Perl. The `p5-*` ports are not intended to
 be used as dependencies, as all they do is pull in the corresponding
 `p5.12-*` ports. And what happens if `p5-libwww-perl` suddenly changes one
 day to depend on `p5.16-libwww-perl`? Will `metar` just keep working?

 We will not accept this patch in its present state.
