How to configure with newer Qt libraries

Hi, I have been trying to compile a couple of applications this morning but both have bombed with a Qt problem. In the case of Quanta 2 beta 4 it reads: checking for Qt... configure: error: Qt <>= Qt 2.2.0 Beta1) (libraries) not found. Please check your installation! The Qt version on my system is 2.2.3. Could anyone advise me on how I can sort this. i presume that I add some sort of conditional statement to the command ./configure! thanks -- Stu "The specification said Windows 95 or better, so I installed Linux"
