openbsd 安装Ports

Ports的安装被设置成简单的make和make install了。下面就是怎么安装X11 程序xfig 的例子。你会注意到依赖包被自动发现并完成下载安装。
首先你需要cd到你安装的程序的目录。如果你查找某程序，你也可以更新你的locate database或者使用上面提到的search功能。一旦你进入了安装程序所在的目录，你只要输入make install,如：

$ sudo make install

使用Flavors:
ports树中的许多应用程序支持不同的安装选项，叫做Flavors.假如某port有多个flavors，在编译该port前，你可以通过简单的设置 环境变量来使用这些选项。假如需要多个选项，FLAVOR可以设置成空格隔开的一些想要的flavors。目前，许多ports有支持数据库、支持没有X 的系统

或者附加的网络属性，比如SSL和IPv6的选项。
$ sudo env FLAVOR="no_x11" make install

列出已安装的ports/packages

你可以使用pkg_info得到已安装的ports和packages的列表：
$ /usr/sbin/pkg_info
