請問如何patch? - Linux

請教各位先進
我想在已安裝好的cactiez 0.7上安裝rancid
目前下載之後解壓縮 ./configure
會卡在下面停住

checking Socket.pm version... Socket version 2.006 required--this is only
version 1.82 at -e line 1.
BEGIN failed--compilation aborted at -e line 1.
configure: error: Socket.pm is older than 2.006; upgrade from
http://metacpan.org/pod/Socket

我google到以下網頁似乎可以用patch處理

https://lists.gt.net/rancid/users/8481

patch的內容如下

我之前使用patch都是用檔案
上面這種方式我沒用過
想請問是照貼就可以嗎 另外貼完後要怎麼接到剛剛中斷的./configure ?
或是有其它方式可以處理也請不吝告知，謝謝!!
