The reason XML::Simple doesn't fill the prerequisites is because you have a few
choices of XML parsers to use: XML::Parser or XML::SAX (the default).  Then, if
you choose XML::SAX, you can choose XML::SAX::Expat, XML::SAX::ExpatXS, or
XML::LibXML, which require either expat or libxml2.  I think it will also
fallback to XML::SAX::PurePerl (like most modules which use XML::SAX) . 

You don't need all XML parsers.  You have a choice, and a quite complex one at
that.  The current bundle already includes XML::Parser::PerlSAX (which uses
XML::Parser) or XML::SAX, so it should work regardless.  The only problematic
module is SearchIO::blastxml, which warns you if XML::SAX::Expat is set as the
default parser.
