I've hit the same issue, needing to build with the 10.6 SDK. But I've found that XCode 4.4 doesn't contain this SDK! So I had to put it back, by opening the XCode.app package contents, and going to: XCode.app/Contents/Developer/Platforms/MacOSX.platforms/Developer/SDKs and copying in MacOSX10.6.sdk from my old XCode 3 Developer folder.
Surprisingly enough, this works! When you quit and relaunch XCode, and select the Base SDK for the project, 10.6 appears in the drop-down.
But beware, when XCode installs an update, you'll have to repeat this process, as I found just now after updating to 4.4.1.
