halp! howto config env.rb to look for rmagick gem?

hi,
my rails application is having trouble locating rmagick to use with acts
as attachment. my host put the gem in
/home/myaccount/ruby/gems/gems/rmagick. how do i tell my rails app
rmagick is located there?

i tried

require "/home/myaccount/ruby/gems/gems/rmagick", but that was crashing
my rails app.

and

ENV['GEM_PATH'] = '/home/myaccount/ruby/gems/gems/rmagick'

both still doesnt work. i am using rails 2.0.2

thank you!

bump anyone?
