Tried to solve the problem particularly with rubycas-server which is based on sinatara
Getting this error when running rubycas-server
rubycas-server/usr/local/rvm/rubies/ruby-1.9.2-p290/lib/ruby/1.9.1/psych.rb:148:in parse': couldn't parse YAML at line 167 column 2 (Psych::SyntaxError)

YAML::ENGINE.yamler= 'syck'
