[Scribus] Configure error with qt3.1.0 (scribus 1.0)

[etienne at no-log.org]

Hello everybody
I'm trying to compile scribus 1.0 on my LFS and when running configure I
get this error:

etienne:~/TMP/scribus-1.0$ ./configure --enable-final
--prefix=/opt/kde3.1.0 --with-qt-dir=/opt/kde3.1.0/qt
--with-qt-includes=/opt/kde3.1.0/qt/include

checking for Qt... configure: error: Qt (>= Qt 3.0.2) (library qt-mt) not
found. Please check your installation!
For more details about this problem, look at the end of config.log.
Make sure that you have compiled Qt with thread support!
etienne:~/TMP/scribus-1.0$

I'm sure to have QT (version 3.1.0) compiled with thread support. $QTDIR
and $KDEDIR are correctly set.

What's wrong with that?

Thank you very much

Etienne
