Title: Perl 5.26 update: possible breakage
Author: Andreas K. Hüttel <dilfridge@gentoo.org>
Posted: xxxxxxx
Revision: 1
News-Item-Format: 2.0
Display-If-Installed: >=dev-lang/perl-5.26.0

You have just upgraded to Perl 5.26. This release brings several 
incompatible changes, also as a consequence of fixing a security 
problem [1]. While we have made sure that all resulting build 
failures within Gentoo are fixed, this may not be the case for
runtime issues, and certainly can affect third-party code (e.g.,
"hand-installed" server applications).

Typical errors are 
   "Can't locate inc/... in @INC (you may need to install the inc::... module)"
   "error: ... has no member named ‘op_sibling’"
   "Unescaped left brace in regex is illegal in ..."

Please see the pages [2,3] for details and report bugs if you run
into problems during or after the Perl update.
