Sorry if this is an exceptional newbie post ... Now that pypy has hit v1 I have tried using it for a few test examples, most of this stuff so far is a little bit simple, however one test is to run a django application that I am developing for someone with pypy rather that cpython However when I fire up pypy i get the following from the django application, what am I missing here greg@gregslaptop ~/projects/minesite/minesite $ ./pypy-c manage.py runserver debug: WARNING: library path not found, using compiled-in sys.path Traceback (most recent call last): File "?", line 32, in run_toplevel File "manage.py", line 11, in <module> execute_manager(settings) File "/usr/lib/python2.4/site-packages/django/core/management.py", line 1736, in execute_manager execute_from_command_line(action_mapping, argv) File "/usr/lib/python2.4/site-packages/django/core/management.py", line 1626, in execute_from_command_line translation.activate('en-us') File "/usr/lib/python2.4/site-packages/django/utils/translation/__init__.py", line 66, in activate return real_activate(language) File "/usr/lib/python2.4/site-packages/django/utils/translation/__init__.py", line 29, in delayed_loader from django.conf import settings File "/usr/lib/python2.4/site-packages/django/conf/__init__.py", line 149, in <module> __builtins__['_'] = first_time_gettext TypeError: cannot set items on object

It seems likely that what django ought to be doing is: import __builtin__ __builtin__._ = first_time_gettext And a similar change in first_time_gettext. __builtin__/__builtins__ is a bit subtle and I might be forgetting something, but I think the above is correct. I remember that __builtins__ is somethings a dict instead of the __builtin__ module, but I forget when (and I couldn't find the case with a few simple tests). I think python-dev has pointed out that this is an implementation detail of CPython on several occassions, though, and that explicitly importing the __builtin__ module is the right thing to do.

It's documented in the Python reference manual. <http://docs.python.org/ref/naming.html> -- Nicholas Riley <njriley@uiuc.edu> | <http://www.uiuc.edu/ph/www/njriley>
