为什么我编译安装XFree86不成功啊？

DayAndNight

我可是新装的系统啊。FreeBSD4.7，安装的时候没有选择XFree86，想自己编译安装。
cd /usr/ports/x11/XFree86-4，然后make通过，make install时候就出错了。下面是出错信息的一部分
Installing for XFree86-4.2.0_1.1 depends on executable:xvinfo - not found
Verifying install for xvinfo in /usr/ports/x11/XFree86-4-clients

这里很正常，因为X是一个大包，里面有各个组件，这些包之间也有依赖关系

请把你的错误信息贴全了，否则实在没有办法帮你。

我修改了/etc/make.conf，用的-03参数，会不会是这个的影响啊？
多谢了！
