Comment:

 As far as I can tell, the problem is {{{-mmacosx-version-min=10.7}}} that
 qmake uses in {{{CXXFLAGS}}} and {{{CFLAGS}}}.[[BR]]
 It seems to force the use of libstdc++.

 Having qmake respect {{{configure.cxx_stdlib}}} might be a little
 difficult.[[BR]]
 qmake seems to want its own ecosystem.

 As soon as I get a little bit of time, I will see what I can do.
