Using rmagick for spriting with FireApp

[ghost]

I am running FireApp on Windows 7 64-bit.

I am trying to use the rmagick compass extension (https://github.com/Compass/compass-rmagick-engine) instead of chunky_png to support gif files.

I downloaded the rmagick extension and placed it in C:\fire.app\lib\ruby\compass_extensions\compass-rmagick-engine-7f24c8d

I then added sprite_engine = :rmagick to the project's config.rb and restarted FireApp.

The problem is that when I watch my project, I get this error:

Is there anyway to get this extension to work with FireApp?

@abxccd rmagick requires ImageMagick, but Fire.app does not support it. (we are using Java to solve the cross-platform issue)
