How to update packages(ex. to recent KDE-4.3.5) without using the ports system?

[Luca Renaud]

I tried to update my system from KDE-4.3.1 (came in FreeBSD 8 install CDs)
to KDE-4.3.5( in updated ports system)
but it gives error during the compilation of QT related code(libpng.so not
found for compile of libQTsvg.so,or so).
Are there binaries for KDE-4.3.5 for updating my KDE to 4.3.5 version
without using the ports system?
