Following the instructions here: http://hoishing.wordpress.com/2011/08/23/gdata-objective-c-client-setup-in-xcode-4/
I added GData to my iOS 5 project.  When it's time to archive the project I get the following error:
Undefined symbols for architecture armv7:
  "_OBJC_CLASS_$_GDataServiceGoogleYouTube", referenced from:
      objc-class-ref in DataManager.o
  "_OBJC_CLASS_$_GDataEntryYouTubeVideo", referenced from:
      objc-class-ref in DataManager.o
      objc-class-ref in ListController.o
      objc-class-ref in ShareController.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 checked the build settings for the GData.xcodeproj -> GDataTouchStaticLib, and this is what I set them to as seen by this pic: )

Any help is appreciated, to help get my project archived.
