It's no surprise that the error didn't occur in 2.5a1: the
PyXML-0.8.4 installation on rptownsend's machine was for
2.4; the 2.5 sandbox won't see 2.4's xmlplus. Even if PyXML
was installed on 2.5, the test suite would still refer to
xmlcore, thus bypassing PyXML.

I added a few print statements to the tests - see attached 
file py_243.txt for the results while running on Python-
2.4.3

Interestingly, the error doesn't occur with Python-2.5a1

Martin maintains PyXML AFAIK.  Maybe he has some ideas.  I
suspect this might be even worse in 2.5. Element Tree was
added and there was a name change.  Some of those things
still need to be addressed.

Hi Neal,

I've just built 2.4.3 on a Red Hat Enterpeise Edition WS 
V4.2 machine and this gives the same error.

I've had this vague feeling that I've seen something like 
this before, but couldn't find anything when I searched the 
tracker...

I've now realised that the error is due to a conflict with 
PyXML-0.8.4 which was already installed on both machines.

If I rename the ../site_packages/_xmlplus directory to a 
different name then the error goes away (on the Red Hat 
machine at least, the SUSE machine is at home).

Thanks for letting us know about where the regression
occurred.  Can you do a little more debugging to try to find
the cause and some ideas about how to fix it?

I'm not sure that any developer runs on a system that
exhibits this error.  So it will probably be very difficult
for us to figure it out since we can't reproduce it.

I've just retested with earlier versions.

No error with Python-2.4.1
Similar error with Python-2.4.2
