Tvheadend

Is there any HowTo, to install and configure TVHeadend on a Mac?
I used the latest Git master branch and build it on my Mac (Darwin).
But then I get an upnp-error:
[ERROR] upnp: upnp_thread_multicast - cannot find ip address for interface (null) [e=Undefined error: 0]

And in my web-config no TV-Adapters are listed as Inputs.

How can I solve this?

Thanks for help.
