PyXML-0.7.1, python-2.2.1, and Redhat 7.3

[Steve Drake]

I am having a problem using PyXML with tutorial code that I got at
http://www.ibm.com/developerWorks.  Although this code works on
Windows with python-2.2.1, and works on RH 7.3 with python-1.5.2, I
get an error when attempting to use python-2.2.1 on RH 7.3.  I tried
installing python-2.2.1 and PyXML-0.7.1 from source, but I get the
same error as when using rpm packages.  Any help will be
appreciated...
