The RMagick rubyforge site at http://rmagick.rubyforge.org has been updated 
with the binary gem (win32) of the latest version of RMagick. 

Changes include addition of jpeg2000 support. Let me hear what is missing, 
I will try to put together a comprehensive binary that works for everyone. 

Quote from the release of 1.9.1: 

"A complete list of all the fixes and enhancements in this release is 
available on the RMagick home page: http://rmagick.rubyforge.org. 
RMagick 1.9.1 can be downloaded from: 
http://rubyforge.org/projects/rmagick/

RMagick is an interface to the ImageMagick (www.imagemagick.org) and 
GraphicsMagick (www.graphicsmagick.org) image processing libraries. It 
supports more than 90 image formats, including GIF, JPEG, and PNG. 
RMagick now includes RVG, a high-level 2D drawing API based on SVG. The 
package includes comprehensive HTML documentation."
