perl XML::parser is p5*-xml-parser, not p5*-xml-sax-expat

If that was just a typo, then sadly, we have had many many many prior reports of p5*-xml-parser not being found, though it's clearly there; you can probably find a dozen prior tickets in the issue tracker on this. But as far as I recall it always turned out to be user error, often of the kind where the user did not uninstall and reinstall all ports after upgrading to Snow Leopard, and other times of the kind where the user switched what version of perl they were using. What versions of perl are installed?
