libyaml warning doesn\'t go away, even if you install libyaml
gem install bundler /home/ec2-user/.rvm/rubies/ruby-1.9.3-p392/lib/ruby/1.9.1/yaml.rb:56:in `&l
If using homebrew, a temporary fix that worked for me was to run:
brew unlink libyaml && brew link libyaml
plus you may also need to run:
brew unlink openssl && brew link --force openssl
