 renaming the new port simply to `qt4`? Now that x11 is hardly support (and
 probably not needed), there is no way to keep calling that port `"mac"`.
 That way we could keep the old `qt4-mac` in place for a while (and ports
 that won't be upgraded yet might conditionally keep working), while urging
 everyone to switch to the new `qt4` asap and update the ports to use qt4
 instead of qt4-mac?

 I think it would be less confusing for the "standard" qt{4,5} ports to be
 named qt4 and at5 and let "specialty" ports add a suffix.

 correctly that those ports do not yet have (published) Qt5

 I hope the substantial time and effort René has put into making QT and KDE
 better on the Mac can finally make it's way into MacPorts in whole, pieces
 or spirit. A quick look at the relevant KDE mail lists and issue trackers
 will show an impressive tail of contributions.
