FadeMind [1] filed a deletion request for gtk-engine-mist [2]: Comment bidulock 2015-07-05 22:23 I'm sorry, there are more issues here. It is building 2.91.1, which is for GTK3 only. The package should fall back to 2.21.0 so it builds against GTK2 as advertised in the desc. Also, it should conflict with gtk-engines (from extra), because gtk-engines from extra compiles all engines, not just mist. Then there is the question, what is the need for this package if gtk-engines from extra includes the "mist" theme engine? IMO should be deleted this package.
