gnome-calucation-3.16 will not build without gtksourceview-3.16 which is still version 9999 and gtksourceview-9999 will not build. gtksourcecompletionitem.c: In function ‘gtk_source_completion_item_new_from_stock’: gtksourcecompletionitem.c:380:2: error: unknown type name ‘GtkStockItem’
This is fixed now. Thanks for reporting.
