     To use this build of Zsh as your login shell, add it to /etc/shells.
 
-    If you have administrator privileges, you must fix an Apple miss
-    configuration in Mac OS X 10.7 Lion by renaming /etc/zshenv to
-    /etc/zprofile, or Zsh will have the wrong PATH when executed
-    non-interactively by scripts.

-    Alternatively, install Zsh with /etc disabled:
-      brew install --disable-etcdir zsh
