[CentOS] problem in installing koffice 1.5 from source

hey friends,

I am trying to install koffice 1.5 from source (tar.gz). All the packages needed for koffice are installed that is Qt qt-config-3.3.3-9.3 qt-designer-3.3.3-9.3 qt-3.3.3-9.3 qt-devel-3.3.3-9.3 arts-* kdebase-* kdelibs-devel-3.3.1-3.14 kdelibs-3.3.1-3.14

but I am getting the below error while running the command "./configure" checking for Qt... configure: error: Qt (>= Qt 3.3 and < 4.0) (headers and libraries) not found. Please check your installation!

Can somebody tell me what is missing or the path for qt libraries & headers so that I can give it with ./configure command

Thanks & Regards
