Gentoo updates perl from 5.22 to 5.24

On desktop systems emerge usually complains that there are packages requiring 5.22 and refuses to update:
!!! Multiple package instances within a single package slot have been pulled
!!! into the dependency graph, resulting in a slot conflict:


  (dev-lang/perl-5.24.1-r1:0/5.24::gentoo, ebuild scheduled for merge) pulled in by
    =dev-lang/perl-5.24* required by (virtual/perl-MIME-Base64-3.150.0-r2:0/0::gentoo, installed)
    ^              ^^^^^                                                                                                                                
    (and 8 more with the same problem)

  (dev-lang/perl-5.22.3_rc4:0/5.22::gentoo, installed) pulled in by
    dev-lang/perl:0/5.22=[-build(-)] required by (dev-perl/Digest-HMAC-1.30.0-r1:0/0::gentoo, installed)
    (and 13 more with the same problem)      
To resolve that:

Forcibly update perl (-O), then clean up:
# emerge -1uav perl-cleaner
# emerge -1uavO perl
# perl-cleaner --all
(repeat perl-cleaner if emerge fails)
There may still be perl virtuals that need reinstalling:
# emerge -1av $(qlist -IC 'virtual/perl-*')
This should leave you with a consistent perl build and emerge should no longer suggest a downgrade.

Great notes & Thank you!

Lucky for me I've just returned back to using Gentoo after an absence well over 5+ years. This error was popping up for me on a fresh install (arch=amd64, plasma profile). Highly annoying considering it was a fresh build.
