When RUBY_TARGETS includes ruby2_3 the rdoc ebuild builds for ruby-2.3 However the script that creates /usr/bin binaries is hard coded for 20 21 22 and therefore does not create /usr/bin/rdoc-23 or /usr/bin/ri-23 This is the offending routine: for version in 20 21 22; do if use ruby_targets_ruby${version}; then ruby_fakegem_binwrapper $bin /usr/bin/${bin}${version} sed -i -e "1s/env ruby/ruby${version}/" \ "${ED}/usr/bin/${bin}${version}" || die fi done done This bug causes other ebuilds like hoe to fail
Thanks for the report. This is now fixed with rdoc-4.2.2
