Installing libyaml for ruby on a mac osX (Lion)

Question

I am getting this error message:

\"It seems your ruby installation is missing psych (for YAML output).
To eliminate this warning, please install libyaml and          


        

Answer 1

This worked for me:

• rvm remove 1.9.3
• download http://pyyaml.org/download/libyaml/yaml-0.1.4.tar.gz
• cp Downloads/yaml-0.1.4.tar.gz .rvm/archives/
• rvm install 1.9.3
