Xcode linker failing when building Unity3D iPhone project

Question

Unity is able to build the Xcode project but when I go to build the project to my iPhone it throws 50 warning(I heard this is fine with a Unity project) and it fails at the linker.

It seems that maybe the reference for the library is messed up. Try removing the reference and adding it again. See these similar questions for more info on how to do that and other suggestions.
