 Status: Pending => Rejected

ZC does not bundle expat with its binary builds of python.  

The windows binaries are distributed unaltered -- the PythonLabs build of python for windows does include the expat library, but ZC has never included this as part of python for a linux binary release.

At one point in time, Zope did include an older version of expat, but this has since been removed.

Linux users needing expat should use a source release of Zope compiled against a local python.

This still happens with 2.6.1b2 binary release for Linux.

Another symptom is:

# ./bin/python 
Python 2.1.3 (#1, Sep 19 2002, 13:15:46) 
[GCC egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)] on linux2
Type "copyright", "credits" or "license" for more information.
>>> from xml.parsers import expat
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "/home/zope/testzope261b2/lib/python2.1/xml/parsers/expat.py", line 4, in ?
    from pyexpat import *
ImportError: No module named pyexpat

Yes, this happened to me too.

Basically it means that you cannot use XML zpts using
a binary install.

I'm surprised the unit tests don't detect this.
Actually I'm not sure I ever ran the unit tests using a binary
install...

Binary installation missing pyexpat.so

PageTemplates with non-standard content type ("text/vnd.wap.wml" for example) gives a Site Error with the traceback:

If pyexpat.so is copied from some other Python 2.1 installation the problem goes away.
