I got the same error yesterday. But I think they haven't fix it for the latest stable version. So maybe you can try to install unstable version of master with this command according to document. I tried and it works for me.

brew install --HEAD grafana/grafana/grafana

I had the same problem last Wednesday but it seems to have been fixed by now. Here's what I did...

As recommended in https://github.com/Homebrew/brew/blob/master/share/doc/homebrew/README.md#readme:
brew update; brew update; brew doctor

The problem remained but deleting the tar.gz from the brew cache helped:
rm ~/Library/Caches/Homebrew/grafana-3.0.4.tar.gz

[phopper-pivotal]

brew update; brew update; brew doctor

rm ~/Library/Caches/Homebrew/grafana-3.0.4.tar.gz

worked. thanks cvandrei.
