Tmux and GPM on bare tty

I am running Tmux 2.2 on Arch Linux. I tend to use it from a raw TTY console, rather than an xterm in a window manager. I have GPM installed and running, however I cannot seem to get GPM and Tmux to work together at all. I've enabled the mouse functions with setw -g mouse on however, none of the operations actually function. Selecting a panel/window doesn't work; and I cannot use the mouse in mouse-enabled applications running in Tmux, such as MidnightCommander. MC works with the mouse outside of Tmux, but not inside. Is there a way to get GPM and Tmux to get along? Or does tmux rely on X11 to handle the mouse interaction? Thanks in advance!
