I am trying to implement hook_menu_alter in my module, but I am finding that revisioning_menu_alter is always being called after my hook, regardless of what I set my module's weight to. It seems that this is because the revisioning module does not appear in the system table at all, even though it is enabled.
What is going on? How can I make my module's hook get called after revisioning's hook? Don't modules always have to have an entry in the system table?
