Can not rake success

Here is the message:

-- MacVim ----------------------------------------------------------------------
brew cask install macvim
==> Caveats
Cask macvim installs files under "/usr/local". The presence of such
files can cause warnings when running "brew doctor", which is considered
to be a bug in homebrew-cask.

Note that homebrew also provides a compiled macvim Formula that links its
binary to /usr/local/bin/mvim. It's not recommended to install both the
Cask and the Formula of MacVim.
