The unified installer installs Python but not the libxml2 Python bindings
AFAIK (because it would need the libxml2 libs to do that, I'm guessing).
(I'm running the unified installer now to make sure...)

Sure, but you'll need to install the python bindings for the version
of Python that is installed by the unified installer, i.e. 
/opt/Plone-3.0/bin/python (or wherever it is, somewhere in /opt/Plone-3.0 for sure ;-).

To install the libxml2 python bindings in general, see: http://xmlsoft.org/python.html
where it says:

To install the Python bindings there are 2 options:

    * If you use an RPM based distribution, 
        simply install the libxml2-python RPM (and if needed the libxslt-python RPM).
    * Otherwise use the libxml2-python module distribution corresponding to your installed 
        version of libxml2 and libxslt. Note that to install it you will need both libxml2 
        and libxslt installed and run "python setup.py build install" in the module tree.

HTH,

Alex
