Acabo de actualizar a Mavericks (10.9.2) y después de años de uso de MacPorts decidí usar Homebrew. He instalado correctamente el Homebrew, pero brew médico muestra:
brew doctor
Warning: Unbrewed dylibs were found in /usr/local/lib.

Todo esto viene de R. de la aplicación, a partir de la OSX sitio web específico. Ahora, yo prefiero usar el estándar de la R. de la aplicación en lugar de la versión de Homebrew (para un número de razones personales). Puedo ignorar estas advertencias o será un problema?
