[pypy-dev] works in python2.4, fails in pypy

[Maciej Fijalkowski]

Works for me:

fijal at zygfryd:~$ pypy-c
Python 2.4.1 (pypy 1.0.0 build 57237) on linux2
Type "help", "copyright", "credits" or "license" for more information.
Welcome to rlcompleter2 0.96
for nice experiences hit <tab> multiple times
And now for something completely different: ``"peephope" optimizations are what
an optimistic Compiler uses''

If you have old pypy build try pypy-c --oldstyle, otherwise you can
retranslate pypy.
