The message suggests you may not have access to the windowing system,
and the build process needs it to import tk.  Are you building on a
remote box, or as root who may not have access to your user desktop?
If so, you can solve these problems by ssh with -X or otherwise make
sure that you can launch an X window in your build environment.
