There is a google group specifically for Rails, so you might get
better help there.

There is a new way to do this s seen here:
http://www.loudthinking.com/arc/000601.html

and old way seen here:
http://api.rubyonrails.com/classes/ActionView/Helpers/FormTagHelper.html#M000497

My action pack 1.12.5 seems to support just the old one.
api.rubyonrails.com knows nothing about the new one. Maybe this works
in development version (would be 1.2) only

So either change your script to use the old form, or install egderails
(I won't help you with this, I guess it involves getting rails
directly from SVN)
