execfile() - change python version?

[Trung Hoang]

running the following set of commands in a script:
    import xml.dom.minidom
    dom = xml.dom.minidom.parseString(somexmlstr)

using the above in python2.1 from my account: WORKS
using the above in python2.1 from the web: WORKS
using the above in python2.2 from my account : WORKS
using the above in python2.2 from the web : FAILS!

so im forced to used 2.1 because of xml libraries
#!/local/usr/bin/python
as aposed to
#!/local/usr/bin/python2.2

it probably does not work because of some environmental
variable not being set, which when run from the web
fails to find the SAX parser..

fast translation of tracedump:
i execute xml.dom.minidom.parseString(xmlstr) and it fails to create the SAX
reader in the xml.sax.__init__. i believe it is perhaps python can not find
the required libraries in 2.2 but able to find them in 2.1.

here is the raw tracedump:
[('/usr/cs3/thoang/lib/html/q.cgi', 43, '?', 'execfile("handle-projects.py",
namespace)'), ('handle-projects.py', 14, '?', "projects =
mods['xmlagent'].getProjects()"), ('/usr/cs3/thoang/lib/html/xmlagent.py',
16, 'getProjects', 'dom = xml.dom.minidom.parseString(datamine)'),
('/usr/local/lib/python2.2/xml/dom/minidom.py', 965, 'parseString', 'return
_doparse(pulldom.parseString, args, kwargs)'),
('/usr/local/lib/python2.2/xml/dom/minidom.py', 951, '_doparse', 'events =
apply(func, args, kwargs)'), ('/usr/local/lib/python2.2/xml/dom/pulldom.py',
340, 'parseString', 'parser = xml.sax.make_parser()'),
('/usr/local/lib/python2.2/xml/sax/__init__.py', 93, 'make_parser', 'raise
SAXReaderNotAvailable("No parsers found", None)')]

what are your thoughts?
