OAI::Harvester installation help

Hey, all!  Long-time Perl programmer, but new to the world of libraries,
so I'm not all that familiar with all the data formats used in these
parts.

I am attempting to use some code which depends on Net::OAI::Harvester,
but my attempts to install OAI::Harvester are running into problems
with:

- Deep recursion in XML::LibXML::Error::as_string when running 001.ua.t;
I have verified that XML::LibXML is the current (1.70, according to
cpan) version.  This is then followed by A Very Large Number of XML
parser errors, but I assume that's just a side-effect of the deep
recursion preventing the original parse from completing correctly.

- Failures to locate Net::OAI::ListIdentifiers->get_handler in multiple
test files.

- Several failures in other test files either due to undefined objects
or for unspecified reasons, although I'm assuming for the moment that
they are side-effects of the above problems.

Any suggestions for getting this installed properly?  I'm assuming that
this is a case where a simple "force install" isn't going to get me a
working installation...

Complete cpan output of my failed installation attempt is attached.
