I just did a completely new (clean) install of ruby, jruby, and ruboto on a new machine (OSX 10.9). I followed all of the instructions and everything was going great until I got to the 'rake' step of the Getting Started Tutorial.
When I run 'rake' in the auto-magically created 'quick_start' directory I get the following error:
rake aborted!
No such file or directory - ant -version
/Users/KC/quick_start/rakelib/ruboto.rake:12:in ``'
/Users/KC/quick_start/rakelib/ruboto.rake:12:in `<top (required)>'

/Users/KC/.rvm/gems/ruby-1.9.3-p484/bin/ruby_executable_hooks:15:in `<main>'
-Other notes: ruboto setup returns "Ruboto setup is OK!"
