What's up with inventing new USE flag "qt" when we have global USE="qt4" ? cairo-1.10.0-r1.ebuild:IUSE="X aqua debug directfb doc drm gallium opengl cairo-9999.ebuild:IUSE="X aqua debug directfb doc drm gallium opengl openvg qt static-libs +svg xcb" Futhermore, the qt-gui depend is missing a SLOT dep, i.e. qt-gui:4
Looks like when the x11-overlay's version was copied in this blew away the correct depends the the qt4 USE flag.
