Why can't I add subversion package to my OpenBSD 4.5 machine?

What should I add in my init file so that whenever I set up a new machine with Emacs, the required packages install by itself?

• I was setting up my in my new machine I got this error "File error: Cannot open load file,  auto-complete". Now I guess this error is because I don't have  auto-complete package installed in my new machine. (package-initialize) ;; Ask "y" or "n" instead of "yes" or "no". (fset 'yes-or-no-p 'y-or-n-p) ;; Highlight corresponding parentheses when cursor is on one (show-paren-mode t) ;; Highlight tabulations (setq-default highlight-tabs t) ;; Show trailing white spaces (setq-default show-trailing-whitespace t) ;; Remove useless whitespace before saving a file (add-hook 'before-save-hook 'whitespace-cleanup) (add-hook 'before-save-hook (lambda() (delete-trailing-whitespace))) ;; Remove all backup files (setq make-backup-files nil) (setq backup-inhibited t) (setq auto-save-default nil) ;; Save backup files in a dedicated directory (setq backup-directory-alist '(("." . "~/.emacs_saves"))) ;; Add package sources (setq package-archives '(("gnu" . "GNU ELPA Packages") ("marmalade" . "for all your EmacsLisp needs") ("melpa" . "Page on milkbox.net"))) ;; auto complete (add-to-list 'load-path "~/.emacs.d") (require 'auto-complete) (require 'auto-complete-config) (add-to-list 'ac-dictionary-directories "~/.emacs.d//ac-dict") (ac-config-default) ;; smex (global-set-key (kbd "M-x") 'smex) (global-set-key (kbd "M-X") 'smex-major-mode-commands) ;; This is old M-x. (global-set-key (kbd "C-c C-c M-x") 'execute-extended-command) ;; switch window (global-set-key (kbd "C-x o") 'switch-window) ;; yasnippet mode (require 'yasnippet) (yas-global-mode 1) This is my init file contents.
