I have seen other people with the same issue of installing RMagick on Mountain Lion However none of the suggested solutions have allowed me to successfully install rmagick.
Here is the error message I am getting:
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

Can't install RMagick 2.13.1. Can't find the ImageMagick library or one of the dependent libraries. Check the mkmf.log file for more detailed information.
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers. Check the mkmf.log file for more
details. You may need configuration options.
Things I have done:
Installed XCode
Installed the command line tools
Installed XQuartz
Installed homebrew with imagemagick library
Installed most recent version of RVM
Symlinked GCC
Uninstalled and reinstalled both RVM and imagemagick
Any ideas why I still can't download rmagick?
It appears it's a problem reported on the Homebrew github repo (https://github.com/mxcl/homebrew/issues/16625) blaming rmagick itself not supporting newer versions of imagemagick. On that same issue (https://github.com/mxcl/homebrew/issues/16625#issuecomment-11519383), you can find this link: https://coderwall.com/p/wnomjg which actually worked for me. This is what he does:
cd /usr/local/Cellar/imagemagick/6.8.0-10/lib
ln -s libMagick++-Q16.7.dylib libMagick++.dylib
ln -s libMagickCore-Q16.7.dylib libMagickCore.dylib
ln -s libMagickWand-Q16.7.dylib libMagickWand.dylib
Hope this helps.
The latest version of rmagick (2.13.2) now supports imagemagick 6.8
What we did was the following:
cd /usr/local
git checkout 834ce4a Library/Formula/imagemagick.rb
brew install imagemagick
This will install Imagemagick 6.7.7-6
I know this is old, but I have been through a bunch of these responses and still wasn't able to get it to work. I found a random link in another language which actually solved the problem for me (http://sugiarto.webmuapp.com/Package_MagickCore_was_not_found_in_the_pkg_config_search_path). It looks like it was looking for PKG_CONFIG_PATH which was not set up.
What worked for me:
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
Then make sure it worked:
find /usr -name 'MagickCore.pc'
/usr/local/Cellar/imagemagick/6.8.0-10/lib/pkgconfig/MagickCore.pc
/usr/local/lib/pkgconfig/MagickCore.pc
Then try installing rmagick again:
gem install rmagick
Building native extensions. This could take a while...

Installing ri documentation for rmagick-2.13.2...
Installing RDoc documentation for rmagick-2.13.2...
Success! Hope this helps anyone else still running into this issue.
From other answers:
PKG_CONFIG_PATH=/usr/local/Cellar/imagemagick/6.8.0-10/lib/pkgconfig C_INCLUDE_PATH=/usr/local/Cellar/imagemagick/6.8.0-10/include/ImageMagick gem install rmagick -v '2.13.1'
See https://stackoverflow.com/a/10645011/1197775 to know how to get these dirs.
Here is what worked for me on macOS Sierra.
brew uninstall pkg-config
brew install pkg-config
brew unlink pkg-config
brew link pkg-config
I know this is a pretty old issue but it did happen to me recently. I am posting this for those that have tried all other answers and weren't able to resolve so far. Bumping the rmagick
gem to version 2.13.4
has worked with Ruby 1.9.3
on MacOS.
Hope it helps!
