Comment (by devans@…):

 Ok, I did it.

 perl5 port and port group changed to use perl5.22 as the default rather
 than perl5.16 in r143599.

 In addition, in r143602, I've incremented the revision on all the ports
 that use the perl5 port group to create variants since they will all now
 use +perl5_22 as the default variant instead of +perl5_16.

 I've left biblatex-biber and percona-toolkit untouched since they are hard
 coded to use +perl5_22 as the default.  However, I'd urge their
 maintainers to re-write these ports to use the perl5 port group so that
 they will automatically track any change in default perl that may occur in
 the future.
