python-mode on OS X

[Chris Fonnesbeck]

I'm having tremedous difficulty getting python-mode and syntax
highlighting working on emacs in OS X. I byte-compiled python-mode.el,
with the following warnings:

---

I put the following in .emacs to load python-mode on startup:

'(autoload 'python-mode "python-mode" "Python editing mode" t)

but I get the error "Wrong type argument: symbolp, 80" when emacs
starts up, and no python-mode.

Any assistance most welcome; I am running emacs version 21.3.50.4 on
OS X 10.2.6
