Comment puis-je installer numpy sur Python 3.1?

J'ai un serveur Ubuntu 10.10 sur EC2. J'ai installé Python 3.1, et je souhaite maintenant y installer NumPy. Comment fait-on ça? J'ai essayé easy_install-3.1 numpy mais j'ai eu cette erreur:

Le code de cette branche de numpy semble inclure un correctif.
Voici un extrait et les commentaires pertinents:

643         # XXX Hack to get numpy installable with easy_install.
644         # The problem is easy_install runs it's own setup(), which
645         # sets up distutils.core._setup_distribution. However,
646         # when our setup() runs, that gets overwritten and lost.
647         # We can't use isinstance, as the DistributionWithoutHelpCommands
648         # class is local to a function in setuptools.command.easy_install
649         if dist is not None and \
650                 repr(dist).find('DistributionWithoutHelpCommands') != -1:
651             return None
652         return dist

Cependant, si vous ne voulez pas faire cela, essayez python3.1 setup.py install dans le répertoire où vous avez extrait numpy. Cela évite le problème easy_install décrit dans les commentaires de code.
