[Plugin: OStatus for WordPress] not quite passing the ostatus test?

I’ve installed ostatus for wordpress and it’s dependencies with a buddypress multisite on my site machinespirit.net
when I check https://www.madebymonsieur.com/ostatus_discovery/discover.php with https://[email protected] I’m getting a partial win, but it looks like some of the dependencies may not all be working together properly? Do other people’s installs pass the test (meaning it’s just something about my install) or is it the plugin/dependencies.

Also: how does one subscribe to other people on other federated sites like identi.ca?
