p5-Encode-Detect problem

p5-Mail-Spamassassin 升級到 3.2 需要 p5-Encode-Detect , 但是我在 FreeBSD 4.11 (gcc 2.95) 以及之後將 gcc 升級到 3.4.6 都會發生

syntax error before `__attribute__’

的錯誤.

參考 這篇, 解決問題.
修改 lib/Encode/Detect/Detector.xs 檔案

*** Detector.xs.orig Sat Oct 28 04:48:59 2006
— Detector.xs Fri Jun 29 15:07:18 2007

#define PERL_NO_GET_CONTEXT /* we want efficiency */
#include “EXTERN.h”
#include “perl.h”
+ #undef HASATTRIBUTE_UNUSED
#include “XSUB.h”
}

再繼續編譯即可成功.
