Lion OS X tinc issues.

[Matthew Tolle]

used the macport ins ructions.

I've installed tuntaposx.

yeah. I've read that it should be tap0.. but I've no idea how to tell it to use the other. I've tried bridging on and off. I currently use bridging with a second ubuntu server that works just fine. I need the ubuntu bridge up so that's why it's configured the way it is now. 

Thanks,

-Matt
