The installation for rubycocoa isn't working, I get the following error message after typing "ruby /Developer/Documentation/RubyCocoa/Templates/install_templates.rb Xcode4.x" in Terminal

"/Users/agajews/.rvm/bin/ruby: line 6: /Users/agajews/.rvm/bin/ruby: Argument list too long
/Users/agajews/.rvm/bin/ruby: line 6: /Users/agajews/.rvm/bin/ruby: Undefined error: 0"

What do I do?  Please help.
