I would strongly recommend you try homebrew, which is a great replacement for macports:
我强烈建议您尝试自制软件，它是 macports 的绝佳替代品：
Once you get homebrew installed, you should be able to install imagemagick and rmagick very easily:
安装自制软件后，您应该能够非常轻松地安装 imagemagick 和 rmagick：
brew install imagemagick # will take a while!
gem install rmagick

UPDATE: (thanks to JJDand this answer)
Try to install without openpmp if you are having trouble with a chiliproject install:
如果您在安装辣椒项目时遇到问题，请尝试在不使用 openpmp 的情况下进行安装：
brew install imagemagick --disable-openmp
UPDATE X2: (thanks to Ramon Araujo's comment)
更新 X2：（感谢Ramon Araujo的评论）
If you have previously installed imagemagick with homebrew, you will have to unlink it before you install again:
如果您之前已经使用自制软件安装了 imagemagick，则必须在再次安装之前取消链接：
brew unlink imagemagick

Another think to watch out is the version of imagemagick. I had ImageMagick version 6.8.0, which is the latest if you install from homebrew, and rmagick just does not compile with this version. So do a
另一个需要注意的是 imagemagick 的版本。我有 ImageMagick 版本 6.8.0，如果你从自制软件安装，这是最新的，而 rmagick 只是不能用这个版本编译。所以做一个
convert --version
转换 --version
and make sure that your ImageMagick is 6.7 or less otherwise rmagick wont compile..
并确保您的 ImageMagick 为 6.7 或更低，否则 rmagick 将无法编译..
