You can find PPMs for XML::Twig in Kobe's repository: http://cpan.uwinnipeg.ca/module/XML::Twig.

That said, I don't know how you load a 4gb file in XML::DOM, how much memory do you have on that machine? 40gb? With XML::Twig you can process parts of the XML (twigs as opposed to the whole tree ;--) so you should be able to keep memory usage lower, maybe much lower, depending on what you need to do, which should speedup processing. But if you can load the entire tree in memory and you can install libxml2, then you can also try using XML::LibXML, porting the XML::DOM code would be much easier in this case, and XML::LibXML is much faster than XML::DOM.
