如何在Mac Mountain上使用macports配置我的GDB版本Lion Lion

Question

我剛剛使用macports在我的Mac上使用sudo port install gdb在我的Mac上安裝了最新的gdb。問題是當我在命令行輸入gdb時，它仍然顯示舊版本。我怎樣才能切換到我剛安裝的新版本？ 謝謝。

類型：

port contents gdb 

它給你的地方位於港口

/opt/local/bin/ggdb 
    /opt/local/include/ansidecl.h 
    /opt/local/include/bfd.h 
    /opt/local/include/bfdlink.h 
    /opt/local/include/dis-asm.h 
    /opt/local/include/gdb/jit-reader.h 
    /opt/local/include/symcat.h 
    /opt/local/lib/libbfd.a 
    /opt/local/lib/libbfd.la 
    /opt/local/lib/libopcodes.a 
    /opt/local/lib/libopcodes.la 
    ... 

正如你可以看到下面它被命名爲ggdb，而不是用gdb，當你用的MacPorts安裝了
