Linker Error When Integrating iOS and the Google Plus SDK

Question

I'm trying to use the Google Plus SDK for sharing in an iOS 6.1 app and get a linker error after adding the GooglePlus.framework and the GoogleOpenSource.framework.

Merely including the frameworks and building yields the following errors:

Undefined symbols for architecture armv7:
"_CGRectDivide", referenced from:
  -[GTMOAuth2ViewControllerTouch moveWebViewFromUnderNavigationBar] in GTMOAuth2ViewControllerTouch.o
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I've followed instructions found in the Google guide to no avail. I've done the following:

1. Included SystemConfiguration.framework and Security.framework
2. Dragged and dropped the GooglePlus.framework and the GoogleOpenSource.framework from the SDK into my XCode project
3. Added the -ObjC flag to the app target's build settings

In addition to the previous steps I also tried adding the contents of the OpenSource folder provided in the SDK but that had no effect caused additional problems after the initial fix.

Libraries:

I'm not sure what I missed but any help would be greatly appreciated.

Also link in the CoreGraphics framework. It's looking for the CGRectDivide method, which is part of CoreGraphics.
