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

16 There's some #ifdefs lacking around that stuff, as the code where
17 e.g. 'QGnomeTheme::createPlatformMenuBar' is implemented, is inside
18 #ifndef QT_NO_DBUS.

20 Easy way out if you're not depend on gtk-themes in Qt:
21
22 USE="-gtk" emerge dev-qt/qtwidgets
23
24 (and/or put that useflag in /etc/portage/package.use)
25
26 Actually, 5.6.2 had a 'gtkstyle' useflag and no "*gtk*" is in
27 the 5.7.1.ebuild.
28
29 Also, it'll probably work if you reemerge dev-qt/qtgui with "dbus"
30 useflag.
