I've done some experiments with the 8.0 stable branch and the head branch from SVN. I just recompiled /boot/loader but didn't have any luck. The version from the stable branch gives me the exact same error, the head version fails with a new error. Doesn't seem this is really ready at the moment. I think I'll go with a separate mirror pool for now.
