I found the problem: there was a dependency from bluez4 instead of 
bluez5 and then the it was compiled with --disable-bluetooth.

Now the error about the dbus is gone! Thanks for putting me on the right 
direction.
I also verified now the phone is connecting also for headset.

But where I can find the documentation about ofono? I mean, where I can 
learn how to receive and make calls, etc...

Thanks again!
