>From INSTALL: Earlier versions will not work because of a change in where you import things from. Be careful, because now 4DOM wants to go in xml.dom, but pyDOM (that comes with the pyXML package) is also in xml.dom, so clean out the old xml/dom with an 'rm -rf' before installing 4DOM! Note that there is a python-xml-nodom-0.5.5-1.i386.rpm (pyXML without DOM) on the 4DOM site. You may not like RPMS, but perhaps we can mention this in INSTALL. Jeff -- J.W.
