Major-mode 
Debugger entered--Lisp error: (void-variable MAJOR-MODE)
  eval(MAJOR-MODE nil)
  eval-expression(MAJOR-MODE nil)
  call-interactively(eval-expression nil nil)

indent-line-function
ruby-indent-line

(find-library-name "ruby-mode") 
inf-ruby-proc: No current process. See variable inf-ruby-buffer

At this point I have emacs and emacs-starter-kit installed along with 
starter-kit-ruby and starter-kit-lisp
