When updating one of my systems, perl update got in the middle and it seems that portage doesn't try to rebuild dev-perl/glib-perl soon enough, as a consequence, I am blocked with: >>> Emerging (1 of 576) dev-perl/Cairo-GObject-1.5.0-r1::gentoo * Cairo-GObject-1.005.tar.gz BLAKE2B SHA512 size ;-) ...

I know perl-cleaner could solve this but, if I don't misremember, it is planned to deprecate it in the future in favour of handling this "better" with subslots :/
Ah, it is probably a dupe (or depending on) of bug 689644 (similar to bug 596664)
