Rails can't find my Rake Tasks

Hi,
I've added some rake tasks to my rails project but on my production server, rails is not finding the tasks. On my dev box however, rails finds them no problem. They are located in the lib/tasks folder in a file ending in .rake. I do a rake -T and nothing shows up for it. There are a lot of other tasks that show up though.
My production server is Redhat where as my dev is Windows XP.
Any ideas what rails wouldn't be finding the file? The capistrano.rake file is in the same folder and rails finds it.
Cheers,
Eric Goodwin
