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
