LoadError (dlopen(/Library/Ruby/Gems/1.8/gems/rmagick-2.13.1/lib/RMagick2.bundle, 9): Library not loaded: /System/Library/Frameworks/OpenCL.framework/Versions/A/Libraries/libclparser.dylib

It was happening here and I fixed it using:

    gem pristine rmagick

Done! :-)

Ok i got it working now by

1. Uninstalling Imagemagick (i am using homebrew, so i run "brew remove imagemagick"
2. Uninstalling the rmagick gem ("gem uninstall rmagick")
3. Installing the rmagick gem again by running "bundle install"

I hope it helps

This works for me (Ubuntu 12.04, Rails 3.2.12):

sudo apt-get install imagemagick libmagickwand-dev

and then:

bundle
