undefined reference to `media_player_controller_create'

I'm not sure if I'm doing something stupid, but when I try to make I keep getting:

I can see those functions are defined, so I'm completely lost why it keeps failing...
I am trying to compile from a fork, but none of the mentioned files have been changed in that fork:
master...Dreamsorcerer:bluez:master

Hmm, I downgraded to an older version and it built fine. That'll do for me...
