无法在Aquamacs OSX 10.8中设置Python路径

我在我的首选项中使用了这些行

(add-to-list 'load-path "~/Library/Enthought/Canopy_64bit/User/bin")
(require 'python-mode)
(setenv "PYTHONPATH" "~/Library/Enthought/Canopy_64bit/User/bin")

(require 'exec-path-from-shell)
(exec-path-from-shell-initialize)

但当我使用C-C-C时，它仍然使用默认的Apple Python（2.7.2而不是2.7.3 EPD）。默认情况下，EPD正在终端中运行。谢谢，用这个。并将这些行添加到Preferences.el中

(add-to-list 'load-path "~/Library/Enthought/Canopy_64bit/User/bin")
(require 'python-mode)
(setenv "PYTHONPATH" "~/Library/Enthought/Canopy_64bit/User/bin")

(require 'exec-path-from-shell)
(exec-path-from-shell-initialize)
