Note: It looks like you don't have XML::SAX::ExpatXS installed. 
      This is ok since we have XML::SAX::PurePerl to fall back to.
      You might want to consider installing XML::SAX::ExpatXS if you 
      want to boost Net::OAI::Harvester's performance and reliability.

WARNING: It looks like you don't have any XML::SAX parsers installed.

      Please check ParserDetails.ini if appropriate for your version
      of XML::SAX::ParserFactory.

      OAI-Harvester will resort to XML::SAX::PurePerl which has the
      appropriate properties and comes with the XML::SAX distribution.

      For the Build test you may force a specific parser as follows:

NOH_ParserPackage=XML::SAX::PurePerl ./Build test

## a general message about needing to be connected to the net for tests

print <<MESSAGE;

Note: for './Build test' to work you must be connected to the Internet.
The tests use the OAI-PMH repositories at the Library of Congress and OCLC.
