i3blocks 1.5 was released recently. Could you please update the port to the current version?
While you are at it, could you please consider submitting changes required to get i3blocks working with FreeBSD upstream?

1.) i3blocks it's working fine, just tested it on a machine.
2.) This i3blocks version it's a fork of i3blocks. So if you want the i3blocks mainstream feel free to port it, for the moment I don't have the time to do so.
