Building r5647 On Ubuntu Studio 14.04.3 LTS
Things were working great until sometime last week when this bug popped up. When it happens I have made sure build-dep for mixxx are met and that my system's packages are all updated. Not sure what to do past that.
Here is my scons log when: it blows up:

I cannot reproduce this using Ubuntu Trusty and QT 4:4.8.5+
Which Qt version do you use? Is there anything special?
In any case adding the "Missing" Includes cannot hurt.
See commit e4c693f.
