Edit:
I have just realized I am using version 0.2 of auto-complete.el. I think I need to use auto-complete.el version 0.1. Where can I download it from? I can only find the newer version on Google.
I am trying to set up an auto completion for Python in Emacs.
I am using Ubuntu LTS version, I have both Python and Emacs installed.
This is my .emacs file:
(setq-default indent-tabs-mode nil) ; always replace tabs with spaces
(setq-default tab-width 4) ; set tab width to 4 for all buffers
(add-to-list 'load-path "~/.emacs.d/vendor")
(progn (cd "~/.emacs.d/vendor")
(normal-top-level-add-subdirs-to-load-path))
(require 'python)
(require 'auto-complete)
(require 'yasnippet)
(autoload 'python-mode "python-mode" "Python Mode." t)
(add-to-list 'auto-mode-alist '("\\.py\\'" . python-mode))
(add-to-list 'interpreter-mode-alist '("python" . python-mode))
;; Initialize Pymacs
(autoload 'pymacs-apply "pymacs")
(autoload 'pymacs-call "pymacs")
(autoload 'pymacs-eval "pymacs" nil t)
(autoload 'pymacs-exec "pymacs" nil t)
(autoload 'pymacs-load "pymacs" nil t)
;; Initialize Rope
(pymacs-load "ropemacs" "rope-")
(setq ropemacs-enable-autoimport t)
;; Initialize Yasnippet
;Don't map TAB to yasnippet
;In fact, set it to something we'll never use because
;we'll only ever trigger it indirectly.
(setq yas/trigger-key (kbd "C-c <kp-multiply>"))
(yas/initialize)
(yas/load-directory "~/.emacs.d/snippets")

Inside the .emacs.d directory I have:
pymacs.el
init_python.el
vendor/
snippets/
inside the .emacs.d/vendor I have installed pymacs, yasnippet and auto-complete so it looks like this:
auto-complete.el
pinard-Pymacs-4be2c15/
yasnippet-0.5.9/
When I start emacs like this:
emacs -nw manage.py
I get this error message:
![enter image description here][1]
Any ideas how to get it working?
I have been googling for a long time now but I can't find any clear instructions how to get it all working together.
