Bug#40363: configure fails to detect qt

[true42 at bigfoot.com]

Package: kdevelop
Version: KDE 2.2.2 
Severity: normal
Installed from:    Mandrake RPMs
Compiler:          gcc 2.96
OS:                Linux
OS/Compiler notes: Not Specified

I have libqt2-2.3.1-29mdk and libqt2-devel-2.3.1-29mdk installed (usr/lib/qt2), the directory is recognized by kdevelop's path settings.
Still, running configure (even with --with-qt-...) on a new project gives the following error:
"checking for Qt... configure: error: Qt (>= Qt 2.2.2) (library qt) not found. Please check your installation!"

Output of configure.log:
configure:6588: checking for Qt
configure: 6652: /usr/lib/qt2/include/qstyle.h
taking that
tried NO

int main() {
    QStringList *t = new QStringList();
    Q_UNUSED(t);
    QIconView iv(0);
    iv.setWordWrapIconText(false);
    QString s;
    s.setLatin1("Elvis is alive", 14);
    return 0;
}

Is this a bug?

Thank you very much,

Marcus.
