Installing RMagick gem on Mountain Lion show errors 'Abort trap: 6'

Question

I've installed ImageMagick(6.8.6-3) by Homebrew.
When try to install rmagick gem(2.13.2) on Max OS X Mountain Lion, show errors 'Abort trap: 6'

gem install rmagick -v 2.13.2
Abort trap: 6

When switch version to '2.13.1', show errors below.

gem install rmagick -v 2.13.1
Building native extensions.  This could take a while...

I can't figure out what's wrong?

to install rmagick 2.13.1 on mac, you need Imagemagick version 6.7.x (it wont work with 6.8.x). And you may have to run this command before installing the gem

cd "`Magick-config --prefix`/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

The above is actually equivalent of running these commands

cd "`Magick-config --prefix`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

After this, you can

gem install rmagick -v '2.13.1'

And to install ImageMagick 6.7 using homebrew, run these commands

cd /usr/local/
brew versions imagemagick

You should see something like this

6.8.0-10 git checkout 883f549 /usr/local/Library/Formula/imagemagick.rb
6.7.7-6  git checkout 834ce4a /usr/local/Library/Formula/imagemagick.rb
6.7.5-7  git checkout f965101 /usr/local/Library/Formula/imagemagick.rb
6.7.1-1  git checkout be8e0ff /usr/local/Library/Formula/imagemagick.rb
6.6.9-4  git checkout 4e7c332 /usr/local/Library/Formula/imagemagick.rb
6.6.7-10 git checkout 0476235 /usr/local/Library/Formula/imagemagick.rb
6.6.7-8  git checkout db99927 /usr/local/Library/Formula/imagemagick.rb
6.6.7-1  git checkout 7cd042f /usr/local/Library/Formula/imagemagick.rb
6.6.4-5  git checkout 53886de /usr/local/Library/Formula/imagemagick.rb

Then choose your version by running

git checkout 834ce4a /usr/local/Library/Formula/imagemagick.rb

followed by

brew install imagemagick
