I have the same problem...

IRB: irb(main):001:0> require 'RMagick' => true

script/console of my app: Loading development environment (Rails 2.1.0)

require 'RMagick'

=>

include Magick

=> Object

image = Magick::ImageList.new()

=> scene=

But if I use it in a controller: no such file to load -- RMagick

# gem list [snip] rmagick (2.5.2) [/snip]
