qt5-qtwebkit on < 10.9 (without libc++ being default)

[Mojca Miklavec]

Hi,

I have the following port installed:
     qt5-qtwebkit @5.5.1_2 (active)

But after
    http://trac.macports.org/changeset/144467/trunk/dports/aqua/qt5
it no longer compiles:
    Error: qt5-qtwebkit does not support your selected MacPorts C++
runtime. libc++ must be selected and C++-based ports built against it.

I know that libstdc++ is a ticking bomb (I still believe that it would
be great to officially support libc++ with the buildbots), but
nevertheless: is this recent "breakage" intentional?
