It builds and tests ok for me with perl 5.8.8, but I get the same errors when I build with perl 5.8.0.

That doesn't mean that the module can't be successfully used on perl 5.8.0 - it's just that parts of the test suite fail on perl 5.8.0. - which merely proves that the test suite (as opposed to the module itself) is unusable on perl 5.8.0.

If I was stuck with perl 5.8.0, I would probably just install it and see how it goes ... though there's no guarantee that the same approach is advisable for you :-)

Cheers,
