If you're just targetting FreeBSD >= 5.x platforms, your current  
approach is reasonable (assuming you can fix whatever the problem  
is); if you're targetting other platforms such FreeBSD 4, Dfly, OS X,  
or SysV things like Solaris, try installing the libnet port and  
invoke libnet_get_hwaddr().
