There is often confusion here because we install and think of X as one
thing but it is really two parts, the client libraries and the server. 
You need the client libraries (libX11, libXt etc... for barebones X and
the Qt and/or Gtk etc for most other things on linux...) on the nodes as
the X client applications use these on the client side.  You just don't
need the X server application and libraries.  Or you need to have linked
your client application statically.
