llvm-3.7 upgrade error

[dershow]

I just upgraded llvm-3.7 from 3.7.1_0 to 3.7.1_1. During the upgrade I got the following error:

And, as can be seen, then then seemed to install correctly. Is it safe to ignore this error? If not, what does it mean, and what should be done about it?

That's not really an error. Whoever is logging that should not.
