在Ubuntu 10.04上使用graphicsmagick安装rmagick 2.13.1

Question

我之前有一个与ImageMagick一起使用的rmagick gem安装.从禁用OpenMP的源安装ImageMagick.这种安装工作没有任何障碍.但是我试图卸载rmagick和ImageMagick,以便我可以使用适用于GraphicsMagick的版本.

所以我从源代码安装了GraphicsMagick并再次禁用了OpenMP功能.但是,当我安装rmagick时,我得到以下内容:

Building native extensions.  This could take a while...
ERROR:  Error installing rmagick-2.13.1.gem:

Can't install RMagick 2.13.1. Can't find MagickWand.h.

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/ruby1.8

我已经尝试过:

 export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig

并检查文件夹pkgconfig的内容:

freetype2.pc  GraphicsMagick.pc  GraphicsMagick++.pc  GraphicsMagickWand.pc  libpng15.pc  libpng.pc

我在这里错过了什么？
