1) Install the launchd item in /Library/LaunchDaemons, like so:

   sudo cp -vf #{prefix}/net.sshguard.plist /Library/LaunchDaemons/
   sudo chown -v root:wheel /Library/LaunchDaemons/net.sshguard.plist

2) Start the daemon using:

   sudo launchctl load /Library/LaunchDaemons/net.sshguard.plist

   Next boot of system will automatically start sshguard.
