Good, this is a good question.
Point One: the KDE 3.2 version have not specific instructions for build from source code. Only have instructions for KDE 3.1.X.
Point Two: in the KDE 3.2 requeriments says Qt 3.2.3. Again, no instructions about compiling for KDE 3.2, only for KDE 3.1.X
I was tried to compile QT using the KDE 3.1.X method, but I think not run
I am using Debian
