Am trying to install Rekall-2.4.5 and am getting the following error message when running "make config.kde"

linux-3w8s:/home/gavin/Downloads/rekall-2.4.5 # make config.kde
PYTHONPATH=scons/ python ./scons/rkScanner.py \
--make --spec=settings.kde
Checking for KDE3 includes : not found
make: *** [config.kde] Error 1
linux-3w8s:/home/gavin/Downloads/rekall-2.4.5 #


I can't work out if this is a Rekall, Python or KDE problem.

Any help greatly appreciated
