macports(darwinports)是mac操作系统上的一个非常不错的包管理器，可以很方便的编译安装软件，在安装一个软件的时候会将这个软件所依赖的软件环境一起搭建好，这样可以很方便的安装和升级所需要的软件。就像gem一样的方便。

这是macports的安装说明

这是macprots的完整的说明书
用macports*.dmg来安装macports，位于/opt目录下。如果对于port卸载命令卸载软件失败时，可以直接将opt文件夹删除
一般情况使用macports*.dmg安装之后，环境变量中会包含
重启terminal，运行

/opt/local/bin
如果没有添加到
~/.bashrc
里即可。
重启terminal，运行
sudo port selfupdate
更新ports tree和macports版本
－－－－下面是用macports来安装ror环境来说明macports的好用之处：
以前对于ruby的安装是比较麻烦的，需要gnu的readline（比较容易出现很多问题，譬如ldconfig 问题）
现在用macports可以很方便的来安装ruby：

这样安装就可以将ruby及其所依赖的软件环境全部搭建好了，现在可以运行一下
port installed
来查看用port安装过的包及其版本号：
port installed
The following ports are currently installed:
gperf @3.0.4_0 (active)
libiconv @1.13_0 (active)
ncurses @5.7_0 (active)
ncursesw @5.7_0 (active)
openssl @0.9.8k_0+darwin (active)
readline @6.0.000_2+darwin (active)
ruby @1.8.7-p174_0+darwin+thread_hooks (active)
zlib @1.2.3_3 (active)
再下面来安装mysql：
