似乎有很多人遇到过类似的问题，但是，经过大量搜索，我无法找到适用于我的特定架构的解决方案。我正在尝试安装 Pycrypto（作为 Fabric 的子公司）无济于事。
我正在通过 Homebrew 运行 Mac 10.8.2、python 2.7.3 和 XCode 4.6——使用 pip 或 easy_install 安装（我都试过了）。据我所知，问题可能与我的 XCode 版本有关，也可能与我的库有关。XCode 的命令行工具已安装，我已尝试将其放入setenv ARCHFLAGS "-arch i386 -arch x86_64".cshrc 文件中。我也试过了ln -s /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer /Developer。至于图书馆，我尝试通过链接它们ln -s /usr/local/lib/libgmp.dylib /usr/lib/libgmp.dylib- 但这也没有用。
无论我尝试什么角度，错误总是相同的（见下文）。任何和所有的帮助将不胜感激。
