Thanks for looking into this Larry,

I'm wondering - is there anything stopping the OSX builds from moving to
the Qt5/pyqt4 combination? I gather qt4 on 10.10 is unsupported and
probably has a lot of little quirks like this we can't easily fix. I'm
tipping the next OSX release will have even more. But since we're not
relying on a distro and are more or less free to choose dependencies on
OSX, couldn't we switch the OSX build across now?
