kdevelop wont compile :(

[Sidey]

I've compiled and installed most of kde2 (running konqueror in blackbox at the mo) so i know it works. But.. kdevelop complains about the KDE headers not being there. Btw, its using qt-1.45 and not 2.x.

from ./configure --with-qt-dir=/usr/local/qt/ --prefix=/usr/local/kde
i get:
checking for KDE... libraries /usr/local/kde/lib, headers /usr/local/kde/include
checking for KDE paths... compiling
checking for KDE headers installed... configure: error: your system is not able to compile a small KDE application!
Check, if you installed the KDE header files correctly.
root@burns:/usr/src/kde/kdevelop-1.2/kdevelop-1.2#


and at the end of config.log:
configure:5443: checking for KDE headers installed
