【问题描述】：
我正在尝试为 python 开发设置 emacs。
根据我的阅读，建议使用 python-mode.el 而不是 Emacs 22.3 中的默认 python.el。于是我开始了新的冒险。
据我了解，python-mode 有几个依赖项，所以我需要安装rope、ropemode 和ropemacs。然后最重要的是我需要安装pymacs。
问：对吗？
这是我现在的新 .emacs：
(custom-set-variables
;; custom-set-variables was added by Custom.
;; If you edit it by hand, you could mess it up, so be careful.
;; Your init file should contain only one such instance.
;; If there is more than one, they won't work right.
'(inhibit-startup-screen t)
'(tab-width 4))
(custom-set-faces
;; custom-set-faces was added by Custom.
;; If you edit it by hand, you could mess it up, so be careful.
;; Your init file should contain only one such instance.
;; If there is more than one, they won't work right.
)
(setq emacs-config-path "~/.emacs.d/")
(setq base-lisp-path "~/.emacs.d/site-lisp/")
(setq site-lisp-path (concat emacs-config-path "/site-lisp"))
(defun add-path (p)
(add-to-list 'load-path (concat base-lisp-path p)))
(add-path "")
(add-to-list 'load-path "~/.emacs.d")
(require 'psvn)
;; python-mode

(setq auto-mode-alist (cons '("\\.py$" . python-mode) auto-mode-alist))
(setq interpreter-mode-alist (cons '("python" . python-mode) interpreter-mode-alist))
(autoload 'python-mode "python-mode" "Python editing mode." t)
(setq pymacs-load-path '( "~/.emacs.d/site-lisp/rope"
"~/.emacs.d/site-lisp/ropemode"
"~/.emacs.d/site-lisp/ropemacs"))
(setq interpreter-mode-alist
(cons '("python" . python-mode)

(autoload 'pymacs-load "pymacs" nil t)
;; Search local path for emacs rope
;;
;; enable pymacs
;;
(require 'pymacs)
(pymacs-load "ropemacs" "rope-")
现在，当我启动 emacs 时，我收到以下错误消息：
("C:\\opt\\emacs-22.3\\bin\\emacs.exe")
Loading encoded-kb...done
Loading regexp-opt...done
Loading easy-mmode...done
Loading wid-edit...done

An error has occurred while loading `c:/opt/cygwin/home/akong/.emacs':
File error: Cannot open load file, pymacs
To ensure normal operation, you should investigate and remove the
cause of the error in your initialization file. Start Emacs with
the `--debug-init' option to view a complete error backtrace.
For information about GNU Emacs and the GNU system, type C-h C-a. [2 times]
让它稍微复杂一点：
出于工作原因，我必须使用 python 2.4，但我的 PC 上安装了 python 2.6。但显然rope不喜欢2.4所以我没有运行setup.py。我解压/解压缩这些包并将这些文件放在 ~/.emacs.d/site-lisp 下。默认情况下，如果在命令提示符下调用 python，它是 python 2.4 可执行文件。
问：如何才能成功加载“pymacs”？
