port install not work for me. it always return "Error: Port ImageMagick not found" if you failed installing with port, you can download pkg and install it directly from http://cactuslab.com/imagemagick/
端口安装对我不起作用。如果使用端口安装失败，它总是返回“错误：找不到端口 ImageMagick”，您可以从http://cactuslab.com/imagemagick/下载 pkg 并直接安装它
