What do you mean by "N/A"?

If you look at the Testers Matrix for the latest version of AI::Embedding, you will see "N/A" for Perl version 5.8.9. This is because my module specifies that it requires a minimum Perl version of 5.10, so testing under an earlier version of Perl makes no sense.

If instead, we look at the test results for the version that was the topic of this thread, everything is "N/A". I couldn't understand why until SankoR helpfully explained it in Re: CPAN Testers shows N/A
