Cómo corregir múltiples errores al instalar Homebrew en OSX Lion (principalmente relacionados con OSXFUSE y Mono)

Estoy tratando de instalar Homebrew pero recibo múltiples errores cuando se ejecuta brew doctor.

Soy un completo novato en esto y he intentado desinstalar Homebrew y volver a instalarlo, pero aún no funciona.

Esto es lo que muestra:

Warning: /Library/Frameworks/Mono.framework detected
This can be picked up by CMake's build system and likely cause the build to
fail. You may need to move this file out of the way to compile CMake.

Warning: Unbrewed dylibs were found in /usr/local/lib.
If you didn't put them there on purpose they could cause problems when
building Homebrew formulae, and may need to be deleted.

Unexpected dylibs:

¿Alguien podría ayudarme? ¿Qué es Mono? No recuerdo haberlo instalado. ¿Cómo puedo saber qué programas que uso están usando Mono? Si no son importantes, ¿tal vez podría desinstalar Mono? Y parece que muchos otros errores se basan en OSXFUSE. ¿Podría moverlos a otro lugar? ¿Hay otra forma que no sea desinstalarlo? Un millón de gracias.
