qt4-mac using wrong g++

[Frank J. R. Hanstick]

Hello,
	I keep getting the following error when trying to upgrade qt4-mac:

:info:configure error: The compiler (/usr/bin/g++-4.0) does not seem  
to support the Objective-C blocks (^), which are used by Qt when  
compiling on Mac OS X.

Why is qt-mac trying to use /usr/bin/g++-4.0 to build?
