Do you have the latest iPhone development kit installed? I don't believe you do if you are using Xcode 3.1; 3.2 and up are the current releases.

Location.m:33: warning: 'CLLocationManager' may not respond to '-headingAvailable'

Specifically, this indicates that the declaration of CLLocationManager does not have the -headingAvailable method. That method was added in iPhone OS 3.0. Thus, I'd bet you have the 2.x series of the dev kit installed?
