Rails and OS X: How to install rmagick?

Question

rmagick has a problem working with imagemagick (>= 6.8.0-10) from homebrew.

You can either

update rmagick gem by

    bundle update rmagick

or manually symbol link some dylib to make it work:

    $ 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 that gem install rmagick should work.

Check the discussion about this in homebrew/issues/16625

Update:
Thanks @faraz for the nice one-liner command:

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
