There's a gtk_tree_view_column_clicked () that emits the clicked
signal but it's not wrapped (as you said, there's no #clicked method).
"Manually" emitting the signal should work :

GtkSignal.emit_unit viewcolum#as_column GtkTree.TreeViewColumn.S.clicked

All event-related methods and signals are in an #event sub-object. So,
with 
 button#event#connect#button_press callback
you should be able to detect righ-clicks.

Note that sometimes you have to modify the event mask so that the
events you're interested in are reported : button#event#add .
