我从 DMG 安装了 Macports 1.8.2。安装似乎没问题。我运行sudo port selfupdate以确保我的端口树是最新的。然后我尝试安装，bindfs因为我想在我的 OS X 文件系统中挂载一些目录（就像在 Linux 中一样mount --bind）。
pkgconfig和macfuse是 的两个依赖项bindfs。bindfs由于安装 时出错，我在安装时遇到了麻烦pkgconfig，因此我尝试直接安装pkgconfig，以下是 的调试输出sudo port install pkgconfig：

我最近才安装了 Xcode 3.2.2（在安装 macports 之前）。我是否正确地认为这是这里的问题：
configure: error: C compiler cannot create executables
答案1
使用 UNIX 开发工具重新安装 Xcode 使我能够安装 pkgconfig。
