I don't have an answer to your question (Kevin Krammer is a kde dev
active on the lists, who usually has the best answer to developer-level
questions; I expect he'll be around with an answer shortly...), but...
Unless your project is one-shot, effectively abandonware, I'd strongly
encourage you to go with qt5 at this point. Qt5 very likely also
explains some of the staleness you're seeing in the ruby bindings you
mention above, altho not being a dev (only a relatively advanced gentoo
user and admin accustomed to doing my own builds, as well as following
some developer-context discussion), the last is only speculation on my
Qt4 (and kde4) remains the most available and used on Linux at least for
now, but kde5 is out there now and the leading edge distros are beginning
to ship it, so I expect most will be before the end of the year. After
that, kde4-desktop's time is very limited (tho unlike the kde3/kde4
update, there are efforts this time to keep kde4 supported at the app
level in kde5, and even some of the big ones are likely to remain qt4/kde4
for another year or two), and with it gone, the focus will very quickly
move to qt5.
I'm less sure about other platforms, but believe qt5 is actually better
supported on at least some of them, already.
So for a new qt-based project starting now, as I said unless it's
effectively one-shot abandonware, I STRONGLY recommend a qt5 base as if
you don't start with it now, you'll likely be moving to it rather soon
for ongoing development.
Meanwhile, qt5 is considerably more flexible from a developer perspective
as well, much more modular, with the possibility of only requiring the
modules you need. Meanwhile, big qt-based projects such as kde are
becoming much more modular as well, with some of the more basic kde
functionality now incorporated in qt5 modules, and most of the remaining
basic kde functionality exposed in the kde-frameworks modules, also
optional, such that many formerly kde-based projects are now primarily qt-
based, possibly with a kde-frameworks module or two as dependencies as
well (instead of all of kdelibs4). IOW, the line between the two is
considerably blurred from a qt-developer perspective, and the rather
stark choice between qt-only functionality and including the richness of
kde but at the cost of formerly huge kdelibs as a dependency, is now
pretty well entirely gone.
So again, qt5 would seem to be the way to go, picking the modules you
need and adding to them if you like with a few selected kde-frameworks
modules. Further, given that on other platforms (such as MS Windows)
static linking is much more common, going qt5/kde-frameworks modularity
has the potential to shrink app distribution sizes there dramatically,
without unduly shorting yourself in the library functionality department.
Finally, while I don't know the status of qt5 ruby bindings, its worth
mentioning that qtwebkit5 appears to have a build-time (not runtime, tho)
dep on ruby, at least according to the qtwebkit-5.4.1.ebuild package I
have installed here. So (somewhat to my displeasure as I have no other
need for ruby here, and that pulls in a bunch more ruby infrastructure),
at least people building qtwebkit5 are already likely to have ruby
installed as a result of that. As a result, I'd say chances are pretty
high there's active ruby bindings for qt5. =:^)
