As Alberto writes, Qt5 is not usuable with KDE 4. The situation is this:

 - KDE4 is QT4-only.
 - Qt5 is sometimes source-incompatible with Qt4
 - Qt5 introduces a strong emphasis on QML, which is new (relative to Qt4) 
technology, although it's been available for, what, 2 years already.
 - With Qt5, KDE is now "KDE Frameworks" and "KDE Applications", and the 
entire layout of the packages they ship is changed; some things have moved 
from kdelibs (developed in KDE4) into Qt, and the whole stack has become much 
more modularized (some might say "fragmented", but that's only if you're 
building it yourself).
 - KDE Frameworks makes heavy use of the QML from Qt5.
 - I gather Qt5 is a hard nut already on FreeBSD
 - KDE Frameworks probably contains a year and a half of mostly-Linux 
development and will be quite a challenge.
