Installing QT4.7 for Cocoa

Hi, I have previously been using QT4.7 with Carbon on Leopard; now I am running Snow Leopard and want to use Cocoa based QT, both 32 and 64 bit.

I installed the QT SDK 4.7 for Mac because I found some posts that suggested it contained the Cocoa based framework (it didn't seem to). I went on to install the 4.7.1 binary framework for Cocoa. However when I check it seems to be Carbon still :confused: :

Code:

$ otool -L /Library/Frameworks/QtGui.framework/QtGui
/Library/Frameworks/QtGui.framework/QtGui:
	QtGui.framework/Versions/4/QtGui (compatibility version 4.7.0, current version 4.7.1)
	QtCore.framework/Versions/4/QtCore (compatibility version 4.7.0, current version 4.7.1)
	/System/Library/Frameworks/Carbon.framework/Versions/A/Carbon (compatibility version 2.0.0, current version 152.0.0)
	/usr/lib/libz.1.dylib (compatibility version 1.0.0, current version 1.2.3)

	/System/Library/Frameworks/Foundation.framework/Versions/C/Foundation (compatibility version 300.0.0, current version 751.29.0)

Do I have to build QT from source myself ?
