Problems at building the KDevelop-2.1.x

[Iztok]

Platform: (ix86, SuSE 8.1) gcc-3.2, autoconf-2.53, automake-1.6.3, 
kdevelop-2.1.3, qt-2.3.2, qt-3.0.5

I have followed the proposed build procedure for kdevelop-2.1.x at 
http://www.kdevelop.org/index.html?filename=branches_compiling.html

a debug-compiled version:

       $ export KDEDIR=/where/your/kde2/or/kde3/is
       $ export QTDIR=/where/qt-2.3.1/or/qt-3.0.x/is
       $ export LD_LIBRARY_PATH=$QTDIR/lib:$KDEDIR/lib:$LD_LIBRARY_PATH
       $ export LIBRARY_PATH=$QTDIR/lib:$KDEDIR/lib:$LIBRARY_PATH
       $ export PATH=$QTDIR/bin:$KDEDIR/bin:$PATH

       $ export CXXFLAGS="-g3 -O0"

       $ make -f admin/Makefile.common cvs-clean
       $ make -f Makefile.cvs
       $ ./configure --enable-debug --prefix=$KDEDIR
       $ make
       $ make install (as root)



configure script reports as follows:

checking for Qt... configure: error: Qt (>= Qt 3.1 (20021021)) (library 
qt-mt) not found. Please check your installation!
For more details about this problem, look at the end of config.log.
Make sure that you have compiled Qt with thread support!

I have tried seting the QTDIR both to 2.3.2 and 3.0.5 with the same 
(negative) result
I have also built the proect file over the kdevelop project directory 
with the same (negative) result

What have I done wrong ?
