You don't need a PyPy at all, pre-compiled or not.  You don't need
virtualenv either.

As documented at various places, you run the tests by saying:

    python ../../../test_all.py test_rstm.py

typically with "python" being the CPython interpreter.

That's expected: the branch adds stm-only tweaks and doesn't try to
integrate non-stm so far.  But that's also a pointless example,
because bpnn.py doesn't use multiple threads.  The only fully-compiled
multithreaded demo using stm is in
pypy/translator/stm/test/targetdemo.py, which you can use instead of
bpnn.py in the line above.

You are getting this because the support is only good enough to run
targetdemo.py.


A bientôt,
