Created attachment 457378 [details] build.log rdoc-5.0 appears to be missing a dependency on bundler. I've attached a build.log showing the failure w/o bundler installed, if I install bundler manually then the rdoc build succeeds. Thanks!
I can confirm emerging dev-ruby/bundler helps a lot ;)
(In reply to Xavier Miller from comment #1) > I can confirm emerging dev-ruby/bundler helps a lot ;) I confirm the same, dev-ruby/bundler must be added as a dependency for dev-ruby/rdoc ;)
installing dev-ruby/bundler does wonders.
Fixed by avoiding the need to have bundler installed, thanks for reporting.
