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 imagemagick

I have added --disable-openmp option, it also doesn't go well.
$ brew install imagemagick --disable-openmp
brew doctor command result has no problem.
$ brew doctor
Your system is ready to brew.
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
