在 CentOS 中安装 ImagMagick 和 rmagick gem

Question

I know this has been asked several times, but the problem is they bring in new versions of rmagick and the older methods are not applicable now.

Server - CentOS release 5.6 (Final)
Ruby - ruby 1.8.6 (2007-09-24 patchlevel 111) [i386-linux]
Rails - 2.3.5

I tried to install rmagick gem through these steps. I was root user when I executed these queries:

yum install ImageMagick.i386
yum install ImageMagick-c++-devel.i386
gem install rmagick

The first 2 commands executed smoothly without any errors. On gem install rmagick , I am getting this error:

ERROR:  Error installing rmagick:
    ERROR: Failed to build gem native extension.

/usr/bin/ruby extconf.rb
checking for Ruby version >= 1.8.5... yes
checking for gcc... yes
checking for Magick-config... yes

Warning: Found a partial ImageMagick installation. Your operating system likely has some built-in ImageMagick libraries but not all of ImageMagick. This will most likely cause problems at both compile and runtime.
Found partial installation at: /usr
checking for ImageMagick version >= 6.4.9... no
Can't install RMagick 2.13.1. You must have ImageMagick 6.4.9 or later.

My question is how can I install a version > 6.4.9 of ImageMagick . Isnt yum install supposed to install latest version of ImageMagick? or should I try an older version of rmagick gem? In that case, does any one know the older version numbers of rmagick gem?

The version of ImageMagick in the CentOS yum repo is outdated. This kind person has provided updated packages: Problem installing RMagick rubygem on Centos 5
