TL;DR: please drop net-irc/irssi-0.8.15* (once .16 is stable everywhere) To be able to make full use of subslot-triggered rebuilds at Perl updates, the Perl team intends to make perl-module.eclass and perl-app.eclass support only EAPI=5 (and eventually later EAPIs) in the foreseeable future. Please consider, where applicable, * bumping the newest version of your package to EAPI=5 * stabilizing an EAPI=5 version * dropping old versions to the end that at some point all non-EAPI=5 versions have been removed. Thank you!
done.
