Re: Upgrading expat for apache question

That is not your problem, quoting:

http://code.google.com/p/modwsgi/wiki/IssuesWithExpatLibrary

which is more up to date in respect of this issue, even if the
mod_wsgi variant of that document:

"""Note that this only applies to Python versions prior to Python 2.5.
>From Python 2.5 onwards, the copy of the "expat" library bundled in
with Python is name space prefixed, thereby avoid name clashes with an
"expat" library which has previously been loaded."""

You are using Python 2.6, so you cannot be affected by this problem.
