This seems a little silly, but "emerge rsync" is ambiguous because of the new merge-without-package-group feature. "emerge net-misc/rsync" still works fine of course ... I don't know what should be done (if anything) about it.
don't see this as being a big issue. If you want to specify the file, you can use the cat/pkg syntax.
