[Zope] Another plea about Large File Support

Hi, The system I'm working on is Debian 2.2 (potato) with a ReiserFS 3.5 partition on it. I'm assured that on this setup, I should be able to have files of up to 4GB in size, currently I get barfage at exactly 2GB :-( What do I need to do to get Python 1.5.2 and Python 2.1 compiled in such a way that I can have a Data.fs bigger than 2GB? Is there anything I need to do to either Zope 2.3.2 or Zope 2.4.0 to make this work in addition to having Python compiled with Large File Support? cheers, Chris
