Yes, I ran into this last week. Test #10 is a test about top-level domain validation. This is a feature that is turned off by default. The test determines if you have a certain module installed. If you don't, then it runs tests 9 and 10. I don't know why test 10 fails, but it does. I have it running in a CGI right now and it's running fine. (Then again, I'm not using TLD validation, either.)
