I am using Homebrew v0.9.5 on my Mac OS X version 10.9.4
When I run the command: `brew install imagemagick, this error occurred.
$ brew install imagemagi
Have you tried a
$ brew update
$ brew install imagemagick --disable-openmp --build-from-source
Apparently that seemed to fix it for me on Mac OS 10.8 (Mountain Lion). Previously I checked out the latest imagemagick brew recipe with "brew versions imagemagick" and "git checkout e68e443", see here and here
