Firstly, this construct is a bit nuts: REQUIRED_USE="ruby? ( ^^ ( $(ruby_get_use_targets) ) ) $(for t in $(ruby_get_use_targets); do echo "${t}? ( ruby )"; done)" That means if any values of RUBY_TARGETS are set ... then USE="ruby" is required. Which is a bit of a mess when RUBY_TARGETS has default values set globally .... It makes more sense that without USE="ruby", that RUBY_TARGETS do nothing. That aside, this looks like a possible issue in rubygems, so I'm CCing ruby@ as well.

Furtermore, you cannot have more than one provider in RUBY_TARGETS, and that is hardly ever the case by default so this ebuild will block building for almost anyone and this is not easy to fix. > That aside, this looks like a possible issue in rubygems, so I'm CCing ruby@ > as well. rubygems is a PDEPEND for dev-lang/ruby, which causes this issue. Most ruby eclasses handle this by adding a dependency, but not ruby-ng (on purpose due to historic reasons).
The bug has been closed via the following commit(s): https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=4e61d05c9aecb3eee317fc1b12b3397f44d0ca91 commit 4e61d05c9aecb3eee317fc1b12b3397f44d0ca91 Author: Hans de Graaff <graaff@gentoo.org> AuthorDate: 2018-04-07 08:38:08 +0000 Commit: Hans de Graaff <graaff@gentoo.org> CommitDate: 2018-04-07 08:38:34 +0000 net-irc/epic5: fix ruby support, bug 650342 Switch to ruby-single.eclass. This fixes bug 650342 but also simplifies ruby dependency handling. Remove the REQUIRED_USE since this will always be a blocker for most people and simply build against the currently selected ruby version provided by ruby-single. This is in effect what the ebuild was doing before anyway. Include correct slot for ncurses. Use EAPI=6.
