No, you said you couldn't upgrade to newer kubuntu because of some missing library. I showed you how to do it - have a minimalistic Ubuntu 12 as a chroot in Ubuntu 14.

I understand QtCreator versus Qt libraries. But, I think I can do a lot of "GUI only" work on the Ubuntu host platform using Qt Designer and Qt4 stuff that will be compatible with what's available (without building qt) on the RPI. So, moving up to Qt5 on the host Ubuntu system would seem to only complicate things. Or, would it be easy to use a QtCreator built for Qt5, have the libraries it needs for running, but build local and target applications using Qt4? Whew....
Qt4 and Qt5 can live side by side. Qt Creator that I gave you a link to contains a bundled Qt5 environment so you don't have to build anything.

I don't want to clobber the qt4 stuff until I understand the above issues better. Are you saying I can configure QtCreator built from Qt5 to use Qt4 for applications it builds?
Just install the thing and stop worrying. I have a single instance of Creator working fine with Qt4 as well as Qt5, both native and cross-compiled. Creator is not tied to developing with any particular version of Qt. It just needs a particular version of Qt to run. And the binary release comes with one integrated which is totally separate from what you have in your system.
