Thanks Armin. I guess I just don't have a recent enough version. This
machine is running Ubuntu 12.04 and I have PyPy from the repos:

$ pypy
Python 2.7.2 (1.8+dfsg-2, Feb 19 2012, 19:18:08)
[PyPy 1.8.0 with GCC 4.6.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
And now for something completely different: ``pypy is a race between the
industry trying to build machines with more and more resources, and the pypy
developers trying to eat all of them. So far, the winner is still unclear''

Traceback (most recent call last):

    import _tkinter # If this fails your Python may not be configured for Tk
ImportError: No module named _tkinter

I'll try installing a newer version...

Looking here there seems to be binaries built for 12.04-14.04:
http://pypy.org/download.html

This one import tkinter without error:
https://bitbucket.org/pypy/pypy/downloads/pypy3-2.4.0-linux64.tar.bz2

$ bin/pypy3
Python 3.2.5 (b2091e973da6, Oct 19 2014, 18:29:55)
[PyPy 2.4.0 with GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.

This one does not:
https://bitbucket.org/pypy/pypy/downloads/pypy-4.0.1-linux64.tar.bz2

$ bin/pypy
Python 2.7.10 (5f8302b8bf9f, Nov 18 2015, 10:46:46)

Is that an obscure crash?
