pypy seems to have a packaging problem

[gpk]

Binary package hint: pypy-dev

On http://codespeak.net/pypy/dist/pypy/doc/getting-started.html#trying-out-the-type-annotator ,
there are instructions for using pypy, specifically:

> To start the interactive translator shell do:
> cd pypy
> python bin/translatorshell.py

but when I do that, I get the following. It seems that some directory is in the
wrong place, or some search path is set wrong. I experimented a bit with
PYTHONPATH and with adding symbolic links, but I don't yet know enough about
where pypy stores things to fix the problem.

$ cd /usr/share/pypy-1.0/pypy
$ python bin/translatorshell.py
Traceback (most recent call last):
  File "bin/translatorshell.py", line 27, in <module>

Similar problems if I run

$ pypy bin/translatorshell.py
