I doubt you really wanted to recompile ruby, didn’t you? I would not recommend you to go with recompilation until you have a strong understanding on what configure script is at least.

Please re-read the reference accurately and follow the appropriate recommendation:

Users without a system libyaml rely on the embedded libyaml and are recommended to update psych to 2.0.5 which vendors libyaml 0.1.6:

$ gem install psych

or, update your Ruby to 2.0.0-p481, 2.1.2 or newer.
