Install Rmagick on Mac OS X

I like to use the standard ruby tools when developing with Rails. So if I have a gem to install, I won’t use ‘apt-get install’ or ‘port install’, I will use ‘gem install’. To install Rmagick the command is:

sudo  gem install rmagick

And the result is :

Building native extensions.  This could take a while…
ERROR:  Error installing rmagick:
ERROR: Failed to build gem native extension.

/usr/local/bin/ruby extconf.rb
checking for Ruby version >= 1.8.5… yes
checking for gcc… yes
checking for Magick-config… no
Can’t install RMagick 2.13.1. Can’t find Magick-config in /usr/local/bin/:/opt/local/bin:/opt/local/sbin:/usr/local/mysql/bin/:/usr/bin:/bin:/usr/sbin:/sbin

*** 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.

Provided configuration options:

Gem files will remain installed in /usr/local/lib/ruby/gems/1.8/gems/rmagick-2.13.1 for inspection.
Results logged to /usr/local/lib/ruby/gems/1.8/gems/rmagick-2.13.1/ext/RMagick/gem_make.out

It seems there are dependencies not installed. To solve this problem, I will use macport and install the necesary libs with the command:

sudo port install tiff -macosx imagemagick +q8 +gs +wmf

After a bunch of compilation, I relaunch my gem command :

sudo gem install rmagick

And “Voila!” it works. Now have fun with RMagick functionalities.
