Dear Friends,

I have installed Ruby 1.9.1 & rails 3.0.0 (beta vaersion) also its
dependencies in my windows xp machine.

I have also installed image magick version 6.6.1 q16.

I need to work on task related to images, so i tried to install rmagick
in my system, rmagick 2.13.1 installed successfully in my system. But i
receive the follwing error while using rmagick in my code,

irb(main):001:0> require 'RMagick'
