Loading Model in Yaml

Am loading the model called "Decode" in my yaml file. When i run the rake db:seed, it runs fine in windows. But dont know why it fails in unix.

Any ideas?

params.yml

<% require 'Decode' i = 0 %>

Filter_Param<%= i=i+1 %>: id: <%= i=i+1 %> filter_param: chapter_status disp_value: Active internal_param: modul_status internal_value: <%= Decode::CHAPTER_STATUS_ACTIVE %> sort_order: 1

In Unix: rake aborted! no such file to load -- Decode

Case sensivity in the file name? Most operating systems, unlike WIndows treat file names, "Decode.rb" and "decode.rb" as different.
