Fatal error: Your default XML parser (XML::SAX::PurePerl) is broken.

  There are known bugs in the PurePerl parser included with version 0.13
  and 0.14 of XML::SAX.  The XML::Simple tests will fail with this parser.

  One way to avoid the problem is to install XML::SAX::Expat - it will
  install itself as the system default XML parser and then you will be able
  to install XML::Simple successfully.
