Mach-O linker error since Xcode 5.1.0f3

I had a working project that I’ve build endless times.
But it was time to upgrade my Unity from 4.6 to 5.1.0f3

Since then I’m not able to build my IOS project anymore and I get 5 Mach-O linker errors that I cannot find a solution to.

Anybody that can help me out? Screenshot added

I fixed the problem it was a plugin that wasn’t up to date that caused trouble.
But now that this is fixed I’ve got a load of new errors…
