An excerpt from gdk-pixbuf-0.22.0-r2.ebuild: RDEPEND="media-libs/jpeg media-libs/tiff =x11-libs/gtk+-1.2* >=media-libs/libpng-1.2.1 amd64? sys-libs/db : <sys-libs/db-2 >=gnome-base/gnome-libs-1.4.1.2-r1" # We need gnome-libs here, else gnome support do not get compiled into # gdk-pixbuf (the GnomeCanvasPixbuf library ) Since gdk-pixbuf can be built without GNOME support, the last line of RDEPEND should be "gnome? >=gnome-base/gnome-libs-1.4.1.2-r1". I have not tested this change with USE="gnome", but it worked fine with USE="-gnome".
This is what I get for not cutting and pasting from my modified ebuild. I actually changed it to "gnome? ( >=gnome-base/gnome-libs-1.4.1.2-r1 )"
