As long as it isn't giving you any problems, it appears that this is both normal and okay. Read this thread...

Bogus error message. SE Linux needs the capability module for full

Sorry, I know it's annoying to see error messages when there's nothing you can do about them, but it really looks like this is just the way this one is. It shouldn't cause you any problems.
Good luck!
