I have no clue. 

I'm actually building the packages in a mach chroot so I only load the
packages needed for building, not the whole distro. That means I don't
see issues with confusion of qt versions because I only install the
newer one (for building). In the spec file I add an "rpath" linker
command so that the muse executable looks into the new qt library before
anything else. It seems to work, at least in a simple test I just did in
