Nope. Broken code from upstream. The usual thinking: "nobody will
compile stuff without dbus". But I do. And you seem to as well. I
guess it's actually dev-qt/qtgui with "-dbus" useflag.

[..]
There's some #ifdefs lacking around that stuff, as the code where
e.g. 'QGnomeTheme::createPlatformMenuBar' is implemented, is inside
#ifndef QT_NO_DBUS.
Easy way out if you're not depend on gtk-themes in Qt:
USE="-gtk" emerge dev-qt/qtwidgets
(and/or put that useflag in /etc/portage/package.use)
Actually, 5.6.2 had a 'gtkstyle' useflag and no "*gtk*" is in
the 5.7.1.ebuild.
Also, it'll probably work if you reemerge dev-qt/qtgui with "dbus"
useflag.
