[Kcachegrind-callgrind] Kcachegrind 0.4.6 : configure: error QT (>= QT3, 0) headers and libraries not found

[Frank C. <fra...@ho...>]

Good morning, We are running Centos-Linux 5.5 x86+32. I just downloaded kachegrind 0.4.6. When I configure it, it complains about QT: configure: error QT (>= QT3,0) headers and libraries not found.
     I downloaded QT SDK for Open source Development on Linux/X11 32-bit in my home directory /home/frankc. 
    When I configure kcachegrind again, it complains about QT: configure: error QT (>= QT3,0) headers and libraries not found even though I downloaded the QT SDK in /home/frankc.
    Is there any other location I should be installing QT in (maybe as root) so that the kachegrind configure can find the QT header and libraries? Thank you.
