A couple of areas in the build process currently require an X
connection.  This should probably be fixed.  Are you building on a
local or remote machine?

  * If you are building on a remote machine, you need to set the
    display or use automatic X forwarding with ssh -X.

  * If you are building on a local machine, I think the problem is
    that when you go to install you are root and root doesn't have
    access to the display.  You can verify this by trying to do

     root> xterm&

    and see if you can get a window to pop up.  If not, you need to
    tell the windowing system to allow connections from root.  

Unix gurus please advise here.  Something like

    user> python setup.py build
    user> xhost +
    user> su
    root> python setup.py install
    root> exit 
    user> xhost -

Let me know!
