I'd guess opie-lrelease-native is a bit outdated for qt4, but I've never 
used it, so I'm not sure.

That wasn't a question of whether we should use build system's qt tools, 
it was about not splitting qt into many native packages, but rather 
using a single qt-native, since, for instance, qmake2-native has to 
build half a qt, anyway, to support qt3 compatibility layer. I don't 
think dropping qt3support is a feasible option. If not, then, of course 
adding a missing lrelease-native is the way to go.
