Can not build after updating world because latest gconf is 1.1: gnome-vfs-1.0.5-r1.ebuild has RDEPEND =gnome-base/gconf-1.0.* but should have =gnome-base/gconf-1.*
No, this is wrong. it should depend on ( >=gnome-base/gconf-1.0 <gnome-base/gconf-1.1 ) gconf 1.1 is unstable branch for gnome2 and not compatible with 1.1.
