Is Qt2 necessary for KDevelop1.1?

[Janne L�hteenm�ki]

I installed KDevelop 1.1 (.rpm) and started reading through the tutorial. I
started a new KDE-mini project and tried to compile it, but g++ couldn't find
header files:
<kcmdlineargs.h>
 <kaboutdata.h>
<klocale.h>
 <qapplication.h>
 <qpushbutton.h>

so I added compiler options:
-I/usr/include/qt -I/usr/include/kde 

Now, when KDevelop starts to check it's enviroment I get error:
checking for Qt... configure: error: Qt (>= 2.0) (headers and libraries) not found. Please check your installation! 

I installed  qt2 and qt-devel.2.0 but that didn't help...
