[Ifeffit] MacPorts now contains Demeter 0.9.22 (and requires Perl 5.22)

Dear Bruce:

Wait a minute! In fact, I updated the Mac Ports package demeter within the last two weeks to use Demeter version 0.9.22. Mac users might want to use the latest version and should consider doing a "port self update && port upgrade demeter".

Users who installed the development version port called demeter-devel will also land on 0.9.22 if they upgrade to the latest.

Note that the latest Mac Ports version is known as 0.9.22_1, where the revision number _1 corresponds to the upgrade from Perl 5.16 to 5.22 (which the MacPorts team is pushing on). For many users, there will be numerous dependency upgrades when you upgrade to 0.9.22_1, but I found they took only a few minutes in my particular case. This change in Perl versions could conceivably cause problems, but I haven't heard of any.

Best wishes,
Joe Fowler
(MacPorts maintainer for demeter)

I don't see the behavior you describe when I follow your recipe.
Perhaps it got fixed when I fixed this fellow's issue...?


Of course, the Mac package is a fair bit behind at this point.
