Swf_fu in rails

[stuckonrails]

Ok, this is my problem. I am trying to embed an .swf file into my webpage using swf_fu. I installed the gem from my applications folder and added the rake task install to my rake file as per the instructions on the swf_fu page found here http://github.com/marcandre/swf_fu. I added the <% swf_tag ""%> erb line into my rhtml file but now when i start the server and try to view the page it throws an swf_tag method not found error. So my question is where did the install of swf_fu go wrong.       Obviously the gem/plugin did not get linked into my project properly. I've also tried adding an require 'swf_fu' to my config enviroment file but that did not help either although this fixed a similar problem i had with will_paginate. Any help would be grately appreciated or else im going to have to redisign my project for javascript rather than using flash.
