Subject: module problems

I'm new at Ruby/Rails, so must have missed something obvious.

I'm trying to use the module "sortable_column_headers", which I obtained 
from https://svn.elctech.com/svn/public/sortable_column_headers/.  When 
I try to load a view that uses this module, I get the following error. 
The line with "before_filter" is this:

	      before_filter :init_sortable_column_headers

I'm running ruby 1.8.4.
