The base ruby install includes ruby-mode. You should probably get that
file plus its support files and put it in your load-path.

The following is some stuff that I've got in my .emacs file. You can
probably get away with just putting the add-to-list and autoload stuff
there.

(autoload 'ruby-mode "ruby-mode"
  "Mode for editing ruby source files")

(add-to-list 'auto-mode-alist '("\\.rb$" . ruby-mode))
(add-to-list 'auto-mode-alist '("Rakefile$" . ruby-mode))
(add-to-list 'auto-mode-alist '("\\.rake$" . ruby-mode))

(add-to-list 'interpreter-mode-alist '("ruby" . ruby-mode))
(autoload 'run-ruby "inf-ruby"
  "Run an inferior Ruby process")
(autoload 'inf-ruby-keys "inf-ruby"
  "Set local key defs for inf-ruby in ruby-mode")
(add-hook 'ruby-mode-hook
	  '(lambda ()
	     (inf-ruby-keys)))
(autoload 'rubydb "rubydb3x" "Ruby debugger" t)
(add-hook 'ruby-mode-hook 'turn-on-font-lock)

(add-hook 'ruby-mode-hook (lambda ()
			    (make-variable-buffer-local 'compilation-error-regexp-alist)
			    (setq compilation-error-regexp-alist
				  (append compilation-error-regexp-alist
					  (list (list
						 (concat "\\(.*?\\)\\([0-9A-Za-z_./\:-]+\\.rb\\):\\([0-9]+\\)") 2 3))))
			    (make-variable-buffer-local 'compile-command)
			    (setq compile-command (concat "ruby " (buffer-file-name) " "))))


(setq ri-ruby-script "~/.emacs.d/ri-emacs/ri-emacs.rb")
(autoload 'ri "~/.emacs.d/ri-emacs/ri-ruby" nil t)

(add-hook 'ruby-mode-hook (lambda ()
			    (require 'speedbar)
			    (require 'rails)
			    (local-set-key [C-c C-o] 'ri)
			    (local-set-key [M-C-i] 'ri-ruby-complete-symbol)
			    (local-set-key [C-c C-a] 'ri-ruby-show-args)))
