XCode does not build Unity3D Project: lib not found

I have Unity3D project and I built it for iOS. If I run it using XCode's simulator it works fine. But if I want to compile it for "iOS Device" or for a physical device connected to my Mac, I get lots of errors and as a result I can't create an Archive. For a testing purpose, I even created an empty Unity3D project, built it for iOS and still get the same errors, although this project does absolutely nothing. The errors are the following:

ld: library not found for -liPhone-lib

clang: error: linker command failed with exit code 1 (use -v to see invocation)

And these are the settings I use:

Architectures: armv7, armv7s, arm64 (also tried removing arm64 without any positive result)
Base SDK: iOS 7.1
Build active: no
Supported platform: iOS
Valid arch: armv7, armv7s, arm64

I use XCode 5.1.1 and Unity 4.5.1 (previously even tried 4.3.2)

How can I build the project and create the Archive?

I've run into the same issue some time ago and it was fixed by replacing quotes under library search path:
