아래와 같은 에러를 내면서 “gem install rmagick”이 실패할 경우, 아래의 “checking for wand/MagickWand.h”를 주의깊게 보자. magickwand 라이브러리가 설치되어 있지 않기 때문에 발생하는 것이다.
root@wminserver:/home/redmine/redmine/redmine-2.4# gem install rmagick

해결방법
libmagickwand-dev를 설치해 줌으로써 해결이 된다. 아래의 명령을 실행시켜보도록 하자.
$ sudo apt-get install libmagickwand-dev
$ gem install rmagick
문제없이 잘 설치 될 것이다.
