Make sure the _server_ allows forwarding the X connection: in
/etc/ssh/sshd_config, you should have

X11Forwarding yes

Then if you log in using ssh -X, the "DISPLAY" variable should be set
automatically (usually to ":10")

I assume you do have an X11 server running on the client (damn the X
terminology is confusing: the machine you're sitting on with the keyboard
and screen is the X server, but the ssh client; the headless remote box is
the ssh server but the app you're running is the X client.)

If you do have a proper X server running, building the app you want to use
should have installed all the needed libs.
