Well here a new patch that make get_Qt more robust.
Debian/unstable has both a /usr/lib/qt3 and a /usr/share/qt3,
but /usr/lib/qt3 hold only qt plugin.

This patch check for a bin subdirectory (needed for moc).

It seems the header file qarray.h is deprecated in QT3 since it is
put the QT2 compatibility stuff.

The doc state that
                     QArray Class Reference (obsolete)
#include <qarray.h>

   The QArray class has been renamed QMemArray in Qt 3.0.

Cheers,
Bill
