Refer to kept-update info on the front page of https://launchpad.net/~canonical-qt5-edgers/+archive/qt5-beta2 regarding where/how to get Qt 5.3. Note that it's not necessarily that PPA itself.
Added "force running all tests" build log. Failing unit tests down from 10 in bug #1317881 to 5 now!
Note though that 3 of these "Failed to create OpenGL context" failures are not in that count of "5". Only 2 of such failures lead to "1 failed" summary which was used for the calculation, but in reality there are 5 OpenGL context creation errors and at least 3 other failures.
