Comment 37 for bug 337759

I've found out the following in openerp-server.py
# ubuntu 8.04 has obsoleted `pyxml` package and installs here.
# the path needs to be updated before any `import xml`
# TODO: remove PyXML dependencies, use lxml instead.
#----------------------------------------------------------
_oldxml = '/usr/lib/python%s/site-packages/oldxml' % sys.version[:3]
if os.path.exists(_oldxml):
    sys.path.append(_oldxml)

According to this, lxml is to use instead of pyxml ??
But I could not found boolean.so in lxml ??
