[Zope-dev] What builds zlib.so?

Hi, I'm trying to compile and use a checkout of the Zope-2_6-branch. I'm compiling it using: usr/local/bin/python2.1 setup.py build_ext -i ...but when I start Zope I get: 2002-09-19T11:15:31 PANIC(300) z2 Startup exception Traceback (innermost last): Module __main__, line 214, in main Module __main__, line 40, in get_storage Module storages, line 4, in ? Module Globals, line 24, in ? Module TreeDisplay, line 14, in ? Module TreeDisplay.TreeTag, line 23, in ? ImportError: No module named zlib Now, in my 2.5.1 source build, there's a zlib.so in /lib/python. In the 2.6 build, there is not. What builds zlib.so? What needs to be fixed so this works? cheers, Chris
