Installing RMagick 2 on CentOS/RHEL 5 it’s not that hard, you just need to install ImageMagick newer than 6.3.5 (CentOS/RHEL 5 is shipping ImageMagick 6.2.8) and that’s the hardest part of the job.
[root@silver ~]# gem install rmagick

Can't install RMagick 2.12.2. You must have ImageMagick 6.3.5 or later.I’ve tried to avoid ImageMagick upgrade and to install RMagick 1, but RMagick 1 failed to install with a strange compile error, probably because the gcc compliler shipped with CentOS/RHEL 5 is too new for version 1.
I didn’t wanted to patch RMagick 1, neither to install from sources (I do prefer RPM packages). So, I’ve decided to upgrade ImageMagick library to satisfy RMagick 2 requirements.
Subscribe your system to the following repositories:
Install the following packages:
[root@silver ~]# yum --enablerepo=epel --enablerepo=rpmforge --enablerepo=centosplus install djvulibre-devel libwmf-devel jasper-devel libtool-ltdl-devel librsvg2-devel openexr-devel graphviz-devel gcc gcc-c++ ghostscript freetype-devel libjpeg-devel libpng-devel giflib-devel libwmf-devel libexif-devel libtiff-devel
Add “–noplugins” if you are using “yum-priorities”, or it will fail to install packages.
Download ImageMagick.spec to your SPECS directory and ImageMagick-6.5.7-0.tar.bz2 to SOURCES directory and then rebuild the rpm using rpmbuild:
[root@silver SPECS]# rpmbuild -ba ImageMagick.spec
[...]
Or just grab the source RPM from here:
http://red.penguin.ro/SRPMS/ImageMagick-6.5.7-0.src.rpm
and build it:
[root@silver ~]# rpmbuild --rebuild ImageMagick-6.5.7-0.src.rpm

We’ll replace occurences of #include <ruby.h> with #include “ruby_macros.h” and create an include file ruby_macros.h with the following content:
#ifndef __RUBY_MACROS__
#define __RUBY_MACROS__
#include <ruby.h>
#ifndef RARRAYPTR
# define RARRAYPTR(v) RARRAY(v)->ptr

RMagick is an interface between the Ruby programming language and the ImageMagick® and GraphicsMagick image processing libraries.
To install RMagick on CentOS 4 you’ll need to install RMagick version 1 because version 2 requires newer version of ImageMagick that’s not available in CentOS 4 repositories.
I do assume that you already have installed RubyGems. If not, then read my post Install RubyGems on CentOS 4.
Let’s start by installing required libraries:
[root@lion ~]# yum install gcc gcc-c++ ImageMagick-devel ghostscript freetype-devel \
libjpeg-devel libpng-devel libpng10-devel libwmf-devel libexif-devel libtiff-devel
[...]Then install RMagick gem specifying version with ‘-v’ switch:
[root@lion ~]# gem install rmagick -v 1.15.14

This post will explain how to install RubyGems 1.2 on the server running CentOS 4.
Following instructions from the install section of the RubyGems User Guide:
http://www.rubygems.org/read/chapter/3
[root@monster tmp]# yum -y install ruby ruby-devel irb
...
[root@monster tmp]# wget http://rubyforge.org/frs/download.php/38646/rubygems-1.2.0.tgz
...
[root@monster tmp]# tar xvfzp rubygems-1.2.0.tgz
...
[root@monster tmp]# cd rubygems-1.2.0
[root@monster rubygems-1.2.0]# ruby setup.rb
Expected Ruby version > 1.8.3, was 1.8.1
Oops, we’ll need a newer version of ruby, by default CentOS 4 comes with ruby 1.8.1 . To install a newer version of ruby we’ll subscribe to testing repository from CentOS. To do this we’ll create a repo file called CentOS-Testing.repo in /etc/yum.repos.d directory:
CentOS-Testing.repo content
# /etc/yum.repos.d/CentOS-Testing.repo
# packages in testing repository
[testing]
name=CentOS-$releasever - Testing
baseurl=http://dev.centos.org/centos/$releasever/testing/$basearch/
gpgcheck=1
enabled=0
gpgkey=http://dev.centos.org/centos/RPM-GPG-KEY-CentOS-testing
Note the line with enabled=0, we’ll enable the repository only when needed. Install ruby from the testing repository:
[root@monster ~]# yum --enablerepo=testing install ruby ruby-devel ruby-libs ruby-irb ruby-rdoc

Now it’s better, we do have ruby 1.8.5 installed on the system. Let’s return to RubyGems install:
[root@monster rubygems-1.2.0]# ruby setup.rb
...
------------------------------------------------------------------------------
RubyGems installed the following executables:
/usr/bin/gem
If `gem` was installed by a previous RubyGems installation, you may need
to remove it by hand.Voila! We have installed RubyGems 1.2 on the CentOS 4 server.
