QT PowerVR Driver Load Fail

On a OMAP3530
I added    

-qtlibinfix E
-qt-decoration-styled -plugin-decoration-default -plugin-decoration-windows
-plugin-gfx-transformed -plugin-gfx-qvfb -plugin-gfx-vnc
-plugin-mouse-tslib -qt-mouse-pc -qt-mouse-qvfb
-qt-kbd-tty -qt-kbd-usb -qt-kbd-qvfb
-plugin-gfx-powervr -opengl es2 -release -no-cups -no-accessibility -reduce-relocations
                    -shared -no-nas-sound -no-sm -no-nis
                    -qt-gif -system-libjpeg -system-libpng -system-zlib
                    -no-sql-ibase -no-sql-mysql -no-sql-odbc -no-sql-psql -no-sql-sqlite -no-sql-sqlite2
                    -no-pch -qdbus -stl -glib -phonon -webkit

to the configure parameters and everything seems to build correctly.

When I boot the image I run "export QWS_DISPLAY=powervr"

Then when I run my app i get the following output

powervr: driver not found


Qt seems to run fine with just the framebuffer driver and the OpenGL ES demos work just fine too.

Some advice would be greatly appreciated.

Could you build the opengl-es Demo in QT4.5 successfully? I can not.

Could you try to export such a enviroment var:QT_PLUGIN_PATH to your plugin directory?
