安装freetype出现如下错误

tiredboy

1. 
   
2. GNU make (>= 3.79.1) or makepp (>= 1.19) is required to build FreeType2.
   
3. Please try
   
4.   `GNUMAKE=<GNU make command name> ./configure'.
   
5. or >&2
   
6.   `GNUMAKE="makepp --norc-substitution" ./configure'.
   

复制代码

接着我使用了GNUMAKE=make ./configure也出现错误
GNUMAKE=make: Command not found

我这下不知道该怎么办了,谁教教我,谢谢
freetype的版本是freetype-2.1.10
系统是freebsd6.0
