Using Ruby 2.3, I found that /usr/bin/rdoc pointed to the incorrect path to rdoc. Switching to 2.2 does not fix this either. #!/usr/bin/ruby23 # This is a simplified version of the RubyGems wrapper # # Generated by ruby-fakegem.eclass : 1.45 $ require 'rubygems' load Gem::default_path[-1] + "/gems/rdoc-5.0.0/bin/rdoc" The path on the last line should be: load Gem::default_path[-1] + "/gems/rdoc-5.0.0/exe/rdoc" This makes Ruby packages build. $ emerge --info

This is fixed with rdoc-5.0.0-r2. Thanks for reporting.
(In reply to Hans de Graaff from comment #2) > This is fixed with rdoc-5.0.0-r2. Thanks for reporting. I hope, we will find soon rdoc-5.0.0-r2 in portage tree. At my systems minitest-5.10.1, dev-ruby/json-2.0.2, power_assert-0.4.1, dev-ruby/net-telnet-0.1.1-r1, dev-ruby/xmlrpc-0.2.1, racc-1.4.14 and dev-ruby/kpeg-1.1.0 do not emerge due to this issue.
