Word Wrap in GNU Emacs for OS X

[S. Eng]

Hi 
I downloaded Andrew Choi's emacs and everything runs fine. I am
running the OS X installed on new Powerbooks. I have

(setq text-mode-hook 'turn-on-auto-fill)
(setq fill-column 70)

These are the same lines as on my Linux. But it is not wrapping.
Everything I type is treated as one line.

Do others have this problem? Suggestions would be appreciated.

Thanks in advance.
