You'll need to set RUBY_TARGETS="ruby24" (or otherwise somehow disable ruby23 deps) to get openssl-1.1.0*

And virtual/rubygems-15 seems to again a dependency of net-libs/webkit-gtk-2.22.4, at least on my system.

After deleting did_you_mean-1.0.2 (emerge -C =did_you_mean-1.0.2), I could reemerge the other packages with the -ruby_targets_ruby23 USE flag. Then I removed ruby-2.3.8-r1 (emerge -v --depclean =dev-lang/ruby-2.3.8-r1) and the subsequent 'emerge -uvDN --backtrack=50 world' did not complain about slot conflicts.
