As the mailing list post says, they removed from Qt5 the ability to do universal builds (i.e. by building once and passing multiple -arch flags), which is why we use the muniversal portgroup (which builds multiple times, passing one -arch flag each time, then lipo's them together). The bug report is about inability to build 32-bit on a 64-bit system, and was fixed.

Why do you say that?
