[Development] Qt 5.0 Beta Performance

[David Boosalis]

Thank you for the reply.

IN anser to your questions, I built Qt 5 with no configure options other
then prefix and used the samegame found in
"Src/Qt/5.0.0-beta1/qtdeclarative/examples/demos/samegame"

ldd on the executable reports:
ldd
./samegame

        linux-vdso.so.1 =>
(0x00007fff5cf23000)

        libQtQuick.so.5 => /usr/local/Trolltech/Qt-5.0/lib/libQtQuick.so.5
(0x00007f9729fe0000)

        libQtGui.so.5 => /usr/local/Trolltech/Qt-5.0/lib/libQtGui.so.5
