Emerging app-office/texstudio-2.10.2 with USE="qt4 -qt5 -video" fails if dev-qt/qtsingleapplication-2.6.1_p20150629 is built with USE="qt4 -X -doc -qt5", with message indicating it cannot find qtsingleapplication.h. Remerging qtsingleapplication with USE="qt4 X -doc -qt5" allows texstudio to build and run.
