checking for KDE libraries installed... configure: error: your system fails at linking a small KDE application!

[Ilian Zarov <ilianz crosswinds net>]

   I'm trying to install caitoo (but this is not so important) . When I run the
configure script it fails at checking for KDE libraries installed... I've
checked that all packages about kde are installed and they are... what's the
problem ? Here is some info : 
-----configure script-----
.. . .
checking for Qt... libraries /usr/local/qt/lib, headers /usr/local/qt/include
checking if Qt compiles without flags... yes
checking for moc... /usr/local/qt/bin/moc
checking for rpath... yes
checking for bool... yes
checking for KDE... libraries /usr/lib, headers /usr/include/kde
checking for extra includes... no
checking for extra libs... no
checking for KDE headers installed... yes
checking for KDE libraries installed... configure: error: your system fails at linking a small KDE application!
Check, if your compiler is installed correctly and if you have used the
same compiler to compile Qt and kdelibs as you did use now
