Comment (by devans@…):

 Replying to [comment:4 gnwiii@…]:
 > Some ports, e.g., logwatch ([https://trac.macports.org/ticket/50323]),
 can run with perl 5.22 but give deprecation warnings.  These warnings may
 come from rarely used sections of legacy perl code, so it seems reasonable
 to follow the perl developers policy to give people time to discover and
 fix deprecated usages.

 Fixed in r145378.  In this case, the upstream developers never noticed the
 problem even though these deprecations have been in place since perl 5.21
 (more than a year).  Moving to perl 5.22 as the default revealed the
 problem resulting in your ticket and an upstream fix.  One more reason why
 we shouldn't promote the use of obsolete perl versions,
