Super witty, however maybe suggest the following install help:

[linux] $ sudo apt-get install libmagickwand-dev

[centOs] $ yum install ImageMagick-devel

[mac] use Homebrew $ brew install imagemagick

Hrm. Gem install rmagick is failing for me as well. Worked on Friday. :(

Worked few weeks ago and now is failing. Nothing have been changed.

I know is very hard to maintain and to keep it working on different platforms, but updating wiki might be a good start. I can't find why is not working.

imagemagick is already the newest version.
libmagickcore-dev is already the newest version.
libmagickwand-dev is already the newest version.
