perl5 variants +perl5_16 +perl5_18 (temporarily) restored in https://trac.macports.org/changeset/144563.

After updating your ports with

sudo port selfupdate

you should be able to reinstall perl5 +perl5_16

sudo port install perl5 +perl5_16

and restore things as they were.

If you've already manually changed everything from p5.16-* to p5.22-* and ports with
perl variants to +perl5_22 no need to go back as this is the way things will be in the (not too distant) future.

Let us know if you have any remaining problems and sorry for any inconvenience.
