How to change toolchain [MacOSX]

[nen777w]

Hi!
Recently I migrate to MacOSX 10.8.4 with QtCreator 2.8.0.
I install XCode and command line tools from AppStore, but unfortunately it include only gcc 4.6 which isn't support futures from C++0x/11
Then I install from macports gcc 4.8 and add it to QtCreator->Preferences->Build & Run->Compilers and specify this compiler in Kit settings.
But as I understand I miss something, because after that qmake generate in Makefile:
CC = /Applications/Xcode.app/Contents/Developer/usr/bin/gcc
CXX = /Applications/Xcode.app/Contents/Developer/usr/bin/g++
but my compiler situated in /opt/local/bin
how to fix it?

I find solution right after the puplic this post.

Specify:
QMAKE_CC = /opt/local/bin/x86_64-apple-darwin12-gcc-4.8.1
QMAKE_CXX = /opt/local/bin/x86_64-apple-darwin12-g++-mp-4.8

Hi,

IIRC you should be using clang with that version of Xcode
