This line is incorrect and may cause problems in a future. You can poke 
maintainer to fix this :)

USE_KDE4 and QT_COMPONENTS duplicate work in some sense. kdelibs4 
depends on lots of qt4 components, so these components could be omitted for 
your port. But you cannot leave QT_COMPONENTS empty, because this will bring 
dependency on whole Qt4.
Also not all kde ports really need rcc_build or uic_build for build (e.g. 
audio/kid3), but cmake fails to find qt if there is no rcc and/or uic 
binaries. So the minimal correct QT_COMPONENTS for kde4 ports will be:
corelib qmake_build moc_build rcc_build uic_build

I'm not satisfied with the situation, and hope I'll will work on this 
somedays.

This will be fixed with update to 4.1.2 (already fixed in area51)
