安装rmagick的问题

Question

系统是centos5.2
imagemagick是用yum安装的，可以正常使用，
我在安装rmagick出现问题。
首先用gem install rmagick出现下面的错误：
[root@localhost web]# gem install rmagick --include-dependencies
INFO: gem install -y is now default and will be removed
INFO: use --ignore-dependencies to install only the gems you list
Building native extensions. This could take a while...
ERROR: Error installing rmagick:
ERROR: Failed to build gem native extension.

/usr/bin/ruby extconf.rb install rmagick --include-dependencies
checking for Ruby version >= 1.8.2... yes
checking for gcc... yes
checking for Magick-config... yes
checking for ImageMagick version >= 6.3.0... no
Can't install RMagick 2.9.1. You must have ImageMagick 6.3.0 or later.

*** 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:
--with-opt-dir
--without-opt-dir
--with-opt-include
--without-opt-include=${opt-dir}/include
--with-opt-lib
--without-opt-lib=${opt-dir}/lib
--with-make-prog
--without-make-prog
--srcdir=.
--curdir
--ruby=/usr/bin/ruby

Gem files will remain installed in /usr/lib/ruby/gems/1.8/gems/rmagick-2.9.1 for inspection.

Results logged to /usr/lib/ruby/gems/1.8/gems/rmagick-2.9.1/ext/RMagick/gem_make.out

其次我用tar包安装，解压后出现下面的问题：
[root@localhost RMagick-2.9.1]# ruby setup.rb
---> lib
---> lib/rvg
<--- lib/rvg
<--- lib
---> ext
---> ext/RMagick

希望能帮我解决下。谢谢了！

checking for ImageMagick version >= 6.3.0
说明你ImageMagick的版本不够
好好看看。
