Answer 1

Slingswarm espera versões mais recentes de valac do que 0.26.1; versões posteriores definem valores padrão para os parâmetros ausentes em Gtk.Grid.attach . Para construir o pacote no Debian 8, mude a linha errônea em slingshot.vala para

this.grid.attach (item, c, r, 1, 1);

e execute make novamente.

(Então, realmente isso é um bug no Slingswarm.)
