I'm not running FreeBSD daily at the moment so I've had little time to keep this up to date. There's also a few things (syscalls that are not yet supported on freebsd) that make it a not 100% functional software, which kind of made me lose a bit of interest in keeping this up to date. However the basic functionality and even some plugins should work. The patch for the update looks sane.
