Rails和OS X:如何安装rmagick?

我已经完全绝望了-我花了整整一天的时间试图将rmagick gem安装到Mac OS X Lion，但这实际上是一个悲剧. 我在Google上看到了许多类似的主题，但没有任何帮助.

I am already completely desperate - I spent whole day with trying to install rmagick gem to Mac OS X Lion, but literally it's a tragedy. I saw many similar threads on Google, but nothing has helped me.

我尝试通过brew完全卸载imagemagick并再次安装(此方法工作正常)，然后再安装rmagick，但是每次尝试安装此gem时，都会出现此错误:

I tried completely uninstall imagemagick via brew and install it again (this is working well) and then to install the rmagick, but every time when I try to install this gem, I receive this error:

Building native extensions.  This could take a while...
ERROR:  Error installing rmagick:
    ERROR: Failed to build gem native extension.

Can't install RMagick 2.13.1. Can't find the ImageMagick library or one of the dependent libraries. Check the mkmf.log file for more detailed information.

*** 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
    --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=/Users/adam/.rvm/rubies/ruby-1.9.3-p327/bin/ruby
    --with-MagickCorelib
    --without-MagickCorelib
    --with-Magicklib
    --without-Magicklib
    --with-Magick++lib
    --without-Magick++lib


Gem files will remain installed in /Users/adam/.rvm/gems/ruby-1.9.3-p327/gems/rmagick-2.13.1 for inspection.
Results logged to /Users/adam/.rvm/gems/ruby-1.9.3-p327/gems/rmagick-2.13.1/ext/RMagick/gem_make.out

无论是通过Gemfile还是通过Terminal安装gem，在两种情况下，我都会得到相同的错误输出.

Doesn't matter if I will install the gem through Gemfile or through Terminal, in both cases I get the same error output.

这是imagemagick的版本: imagemagick-6.8.0-10 .

请给我一些提示或建议，问题可能出在哪里? 非常感谢！

Could you give me please some tips or advance, where could be the issue? Thank you so much!
