Yes, I have a macbook running 10.7 currently. I used the system clang to
build Qt 5.4, though I didn't download and apply all the patches you have
in your macports trac ticket. I only cloned Qt5 5.4 branch, added the QSP
patch and built it fine here. I built it outside of the source tree in a
qt5build folder. I built it twice actually, once with -developer-build and
once without (to install it into /usr/local/Qt-5.4.2 so I can build
qtspeech against it). Does one of the patches on the trac ticket change
QBasicAtomiciInt in any way?
