Description Whilom Chime 2017-07-24 22:21:13 UTC
I've suddenly started having massive difficulty building (or installing rather) ruby dependencies such as dev-ruby/minitest, dev-ruby/did_you_mean, dev-ruby/test-unit.  Looks like an installed files problem?

Once I started having issues I removed dev-lang/ruby and all dev-ruby packages, deleted /usr/lib{64}/ruby, deleted all old dev-ruby/* use keywords, set RUBY_TARGETS="ruby24" and let an emerge ... @world pull in what it would. Proximate cause of the build (or apparently install) failure is: 

/usr/lib64/ruby/2.4.0/yaml.rb:5:in `<top (required)>': 
It seems your ruby installation is missing psych (for YAML output). 
To eliminate this warning, please install libyaml and reinstall your ruby. 

Depending on how emerge... @world orders things any of the above-mentioned packages causes the same install failure, and I assume others would as well.

Notably, dev-ruby/psych and dev-libs/libyaml *are* installed: 

emerge -s psych libyaml

Please attach the logs. Do not use external websites like pastebins, whenever possible. 
External websites are not permanent, 
information will be lost and links may direct to spam or malware instead of the needed information.
Some developers maintain several hundred ebuilds and have to use tools to work with the attachments efficiently. 

The bug is assigned to the ruby team now. It would help, if you can find more details with the help of our support channels. [1]
