title: Installing libyaml Cygwin
body: <p>/usr/local/lib/ruby/1.9.1/yaml.rb:56:in `':
  It seems your ruby installation is missing psych (for YAML output).To eliminate this warning, please install libyaml and reinstall your ruby.</p>
  
  <p>I've downloaded libyaml and ran ./configure, make and make install. They all seem to run successfully.</p>
  
  <p>I'm using rvm and I'm not sure how to uninstall ruby in order to reinstall it. I've tried just running rvm install 1.9.3 and I've also tried rvm remove 1.9.3 and then running rvm install 1.9.3</p>
  
  <p>Anyway, nothing is working. I'm still a noob when it comes to programming so apologies if I'm not making sense.</p>
