I installed Xcode 3.2.6 in default directory(/Developer). I downloaded example code http://examples.oreilly.com/0636920010180/ Download the example code again to start from the scrach.
For just one example, check "Allocating and Initializing Objects" in Chapter 1.
You said you build successfully with the base SDK missing? If you look at the frameworks on the left side 'Groups and Files' pane of Xcode, in which color do the frameworks look? Red? Black? You can't build successfully if they look red.
Right click on any of the frameworks in the Groups and Files pane of Xcode and choose 'Get Info'. Could you please tell me the full path?
