Emacs cannot load auto-complete package

Question

I have Emacs (the latest from the savannah repo) installed, and I used package-install to get auto-complete-20140414.2324. I then followed (or tried to) the instructions at this site. Specifically, I added the following to my .emacs:

(add-to-list 'load-path "~/.emacs.d/elpa")
(require 'auto-complete-config)
(add-to-list 'ac-dictionary-directories "~/.emacs.d/elpa/auto-complete-20140414/dict")
(ac-config-default)

I know for a fact that those directories are where auto-complete-20140414 and its dictionary folder respectively are. However, when I boot Emacs, I get the following warning:

File error: Cannot open load file, no such file or directory, auto-complete-config

There's nothing in the instructions I found about this, and I'm not sure what the issue is. Could someone help me out?

Your configuration is wrong. You need not to set load-path manually for installed packages with package.el. You just call package-initialize as below. package-initialize set load-path for all installed package directories.

(package-initialize)

(require 'auto-complete-config)
(add-to-list 'ac-dictionary-directories "~/.emacs.d/elpa/auto-complete-20140414/dict")
(ac-config-default)
