SSH's X11 forwarding is involves more than simply tunnelling the X11 
traffic accross the SSH connection.

It also creates `X Authority cookies' - a kind of simple password on 
the X11 traffic - using the

    xauth

program.

If xauth is not in the path or the remote side of connection cannot write 
an `.Xauthority' file with the cookie, then the X11 forwarding will not be 
created.

If you make ssh more verbose with

   ssh -vvv

it should tell you if this is the case.
