Was merging gnome today and got an error saying gnome-themes failed during ./configure ... it couldn't find gtk-engines, gnome-themes doesn't depend on gtk-engines and gtk-engines is masked, but as soon as i merged gtk-engines the problem was solved.
it depends on which version of gnome-themes you're merging. the one in ~x86 is currently in testing, that depends on gtk-engines which includes gtk-engines-{metal,crux,redmond95..} the one in x86 currently depends on the individual packages themselves and also has some patch to remove the gtk-engines-2 dependency. tell us which version you were having problems with.
