rmagick and imagemagick bundle/homebrew error - ruby-on-rails

Question

Please see error stack below. I tried uninstall/install of imagemagick via homebrew, 'gem pristine rmagick', and reinstall of rmagick. All have returned the same error. Any help would be VERY much appreciated- been at this for a while now.
$ gem install rmagick
Building native extensions. This could take a while...

Answer 1

Had the same problem, easy fix!
https://github.com/mxcl/homebrew/issues/16625
here is the skinny on the solution (rmagick is broken, and you have to create symlinks to get it to work):
cd /usr/local/Cellar/imagemagick/6.8.0-10/lib
ln -s libMagick++-Q8.7.dylib libMagick++.dylib
ln -s libMagickCore-Q8.7.dylib libMagickCore.dylib
ln -s libMagickWand-Q8.7.dylib libMagickWand.dylib

Answer 2

Alternatively, step back one ImageMagick rev:
(via https://stackoverflow.com/a/9832084/485836)
> cd /usr/local
> brew versions imagemagick
6.7.7-6 git checkout 883f549 Library/Formula/imagemagick.rb
6.7.5-7 git checkout f965101 Library/Formula/imagemagick.rb
6.7.1-1 git checkout be8e0ff Library/Formula/imagemagick.rb
...
> git checkout 883f549 Library/Formula/imagemagick.rb
> brew install imagemagick

Answer 3

A better way to get the headers into the proper place might be to just add the pkgconfig from the imagemagick Cellar to your PKG_CONFIG_PATH.
Adding the following to my ~/.bash_profile and then sourcing it (source ~/.bash_profile) worked for me
export PKG_CONFIG_PATH="/usr/local/Cellar/imagemagick/6.8.0-10/lib/pkgconfig:$PKG_CONFIG_PATH"

Answer 4

Ended up being an issue with rails version, needed to update and reinstall imagemagick/rmagick.

Answer 5

brew install imagemagick
should do the trick. Then reinstall the gems.
