FreeBSD build is definitely fixed with dev #1542163689ee9a81d6105e8ea9a08b6bc96990c3 thanks.
I will try the OSX package now.
BTW for both platforms, if you could wrap all shelled ::execl("/sbin/route|ifconfig ...") type commands somehow so they are printed out on stderr or stdout (whether built in debug mode or not) that would help enormously. There are few calls like this, but they dramatically aid in debugging.
