Hmmm, I had the same problem last year with Qt 5.1.
Since then I've upgraded my project to Qt 5.2.1 and Xcode 5.02 and now I only need that line in my .pro file: (same as yours, works ok)
@config += c++11@Also make sure it is a small c and not a capital C "see my blog post":http://www.tripleboot.org/?p=101

Still no hope. I'm not using Xcode 5.02, I'm not certain if this is the problem.

In Xcode, I have to do the following settings
Build Options:
Compiler for C/C++/Objective-C ———————> Apple LLVM compiler 3.1
Apple LLVM compiler 3.1 – Language:
C++ Language ——————-> C++11[-std=c++11]
C++ Standard Library ———————> libc++ (LLVM C++ standard library with C++11 support) -
You need to inform Qt that libc++ is used instead of libstdc++.

I'm guessing here but I seem to remember, LLVM 3.1 was a bit too old for proper C++11 support, so when LLVM 3.2 came out late 2012, C++11 worked much better in Xcode.
Why not trying upgrade your Xcode... it is not so expensive :-)
EDIT: since you're on Lion, Xcode 5 is not kosher, instead you can update to Xcode 4.6.3, which comes with LLVM 3.2 as well.

I can't upgrade Xcode because my mac version < 10.8 (really sad)

(just edited my prev. post): yeah, I forgot you're on Lion, but as I said, Xcode 4.6.3 is the one you could try...

C++11 is working in Xcode, but I'm facing problem with the proper settings for qmake project. I've posted the settings in Xcode for c++11
