Hi! Why amarok with revision 440587 requires qt4?

checking for Qt... configure: error: Qt (>= Qt 4) (headers and libraries) not found. Please check your installation (and make sure you compiled Qt with -debug - doing symlinks to a -release build of Qt4 will introduce breakage, do not do that -)!
What ca I do?

svn rearrange, you now need brances/KDE/3.5/kde-common/admin, instead of trunk/admin.

err, branches/

thanks!
