I got that too. I presume it's newly supported in GCC4.4?

strndup from V8:
char* strndup(char* str, size_t n) {
// Stupid implementation of strndup since macos isn't born with
// one.
size_t len = strlen(str);
if (len <= n)
return StrDup(str);
char* result = new char[n+1];
size_t i;
for (i = 0; i <= n; i++)
result[i] = str[i];
result[i] = '\0';
return result;
}

for getline do you mind trying #define _GNU_SOURCE 1
before #include <stdio.h> in the offending files? The FreeBSD man pages
mentions that as a way of enabling the GNU version of getline().
