以下软件包 都去我的环境库找到
1 先安装 tcl库
2 安装macports
/opt/local/bin/port 一般装到这里
安装autoconf时提示：
Warning: The Xcode Command Line Tools don‘t appear to be installed; most ports will likely fail to build.
Warning: Install them by running `xcode-select --install‘.
mac, xcode 6.1 安装command line tools 支持,autoconf,automake等
