What is more funny -- there is an entry somewhere in the configuration dialog of KDevelop to set the path to qmake. Well... the funny part is, that KDevelop never checks that when looking for qmake. It has some paths hardcoded, so if you have qmake in some non-default location, it won't find it.
That is strange.
Mine uses QTDIR , not hard coded, as can be seen from the first build line:
cd '/home/kish/vision/projects/autotracker/src' && QTDIR="/usr/lib/qt3" gmake -k -j1 clean && QTDIR=&q
