如何在Solaris 2.6下进行源码程序的安装，需要什么环境
我想安装PPP-2.4.1提示如下：
make
cd chat; make all
cd pppd; make all
cc -I../include -DSVR4 -DSOL2 -O -Xa -xO2 -xspace -W0,-Lt -DPLUGIN  -c  main.c
ucbcc: Warning: "-Xa" redefines compatibility mode from "SunC transition" to "ANSI"
ucbcc: Warning: Option -W0,-Lt passed to ld, if ld is invoked, ignored otherwise

        for Sun WorkShop Compiler C

        The product has not been installed properly.
        There are no license files in following path :
        
                None

*** Error code 1

Current working directory /root/ppp-2.4.1/pppd
