 On darwin11, build fails with above error.

 PortGroup cxx11 1.1
 didn't fix it. Thereafter adding both these:
 configure.cxxflags-append -std=c++11
 configure.objcxxflags-append -std=c++11
 didn't fix it either.

 qt4 is a bit picky/tricky about these things. I may need to edit the build
 file directly and add `-std=c++11` to the QMAKE OJCXX flags, unless there
 is an easier way.

 It seems (in the log) that this build specifically disables `c++11`
 earlier in the build configuration due to `libstdc++` (I guess it doesn't
 see `libc++`, and/or doesn't know what `macports-libstdc++` might be).

 This built fine on 10.6.8 configured to libc++, amongst other systems,
 earlier this year. I have a feeling this may be another example of the
 type of fixes we will no longer have to do once we default to `libc++` on
 all systems.
