FreeBSD用ports安装Firefox不成功

今天在FreeBSD 5.4 Release中安装Firefox， 先更新ports tree到最新版本：

　　FreeBSD# cvsup -g -L 2 /root/ports-supfile

　　然后到Firefox的目录中去执行make:

　　FreeBSD# cd /usr/ports/www/firefox

　　FreeBSD# make

　　没多久，系统就爆出了编译错误：

　　nsHostResolver.h:95: error: ISO C++ forbids declaration of `PRAddrInfo' with no type

　　nsHostResolver.h:95: error: expected `;' before '*' token

　　nsHostResolver.h: In member function `PRBool nsHostRecord::HasResult() const':

　　引起这个问题的原因是Firefox在老版本的nspr上会存在问题，无法通过编译！

　　于是决定安装新版的依赖包：

　　FreeBSD# cd /usr/ports

　　FreeBSD# make search name=nspr

　　查出来有如下几个：

　　Port:

　　nspr-4.4.1_1

　　Path:

　　/usr/ports/devel/nspr

　　Port:

　　dnsproxy-1.13

　　Path:

　　/usr/ports/dns/dnsproxy

　　Port:

　　transproxy-1.5

　　Path:

　　/usr/ports/www/transproxy

　　对他们一一进行make, make install后，再来安装firefox即可！
