I've just uploaded RMagick 1.7.4. This release fixes a problem that 
occurs only when compiling with ImageMagick 6.2.1, the most recent 
release of ImageMagick.

As usual, you can get RMagick at http://rubyforge.org/projects/rmagick/

RMagick is an interface to the ImageMagick (www.imagemagick.org) and 
GraphicsMagick (www.graphicsmagick.org) image processing libraries. 
Supports more than 80 image formats, including GIF, JPEG, PNG. Includes 
2D drawing API. Comprehensive HTML documentation.
