I complained earlier about xfce not emerging without requiring gnome, and I thought that had been fixed, but I've just installed a new _rc2 system, and gdk-pixbuf ( a dependancy of xfce) now requires gnome, so I temporarily pathced the xfce ebuild to require only imlib. What would be nice for packages like gdk-pixbuf would be to have gnome ebuilds and non-gnome ebuilds (for pure gtk+ users) with a "virtual gdk-pixbuf." This philosophy should be rigorously followed for packages with optional (mega!) components.
