Building with Vuforia 4.0 but still getting linker issues for arm64?

Does any one else have issues building 64bit with the new Vuforia 4.0.I am building a project using Vuforia 4.0. I put together the skeleton project and it builds ok before I add in vuforia. But after I add in libVuforia.a, set up the Library Search path and add the Header Search Path I get these linker issues. 

Undefined symbols for architecture arm64:
  "std::__1::__next_prime(unsigned long)", referenced from:
      l19725 in libVuforia.a(libVuforia.a-arm64-master.o)
      l20300 in libVuforia.a(libVuforia.a-arm64-master.o)

ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Has anyone come accross this? Any solutions? 

I am getting the same issues. It was working fine for a couple of builds, and now it will not build and instead gives me the errors shown by the OP. Any help on this would be apprecaited. I will check against the sample project shortly. I am using Unity to build the project.
