The following micro-emacs editors work on amd64. Please consider to keyword them. app-editors/ersatz-emacs app-editors/fe app-editors/jove app-editors/mg app-editors/uemacs-pk
Removing app-editors/jove from this request since its dependency x11-libs/xview cannot be fulfilled on amd64. (I may open a separate bug for it later.)
Keyworded it myself, since kingtaco has confirmed that his permission still holds.
