It is impossible to order the linker search path in such a way that libraries specified as full paths will be picked by the linker.
Directories and libraries involved are:
Directory: /dados/kde/lib contains:
Library: /usr/lib/libqimageblitz.so

Directory: /usr/lib contains:
Library: /dados/kde/lib/libstreamanalyzer.so
Library: /dados/kde/lib/libstreams.so
Library: /dados/kde/qt-copy/lib/libQt3Support.so
Library: /dados/kde/qt-copy/lib/libQtCore.so
Library: /dados/kde/qt-copy/lib/libQtDBus.so
Library: /dados/kde/qt-copy/lib/libQtGui.so
Library: /dados/kde/qt-copy/lib/libQtNetwork.so
Library: /dados/kde/qt-copy/lib/libQtSvg.so
Library: /dados/kde/qt-copy/lib/libQtXml.so
