Would you have an ETA on how long a tutorial for Clustering MQTT across two datacenters would be?

Wonder if you can assist, I see a MAC on your desktop, battling to get a Python program with MQTT functionality to run, it fails on import dbus.
I've gotten breakfast install bus to complete, pip install dbus-python though fails.
any pointers would be appreciated
