Eu desinstalei e instalei o Homebrew 3 vezes agora, porque parece que nunca me permite instalar nada, pois me nega permissões no final da maioria das instalações.
Como exemplo, vou postar este cenário de download libjpeg que estou enfrentando atualmente.
Eu tento instalar o libjpeg e obtenho:
$ brew install libjpeg
==> Downloading https://downloads.sf.net/project/machomebrew/Bottles/jpeg-8d.mountain_lion.bottle.1.tar.gz
Already downloaded: /Library/Caches/Homebrew/jpeg-8d.mountain_lion.bottle.1.tar.gz
==> Pouring jpeg-8d.mountain_lion.bottle.1.tar.gz
Warning: Could not link jpeg. Unlinking...
Error: The brew link step did not complete successfully
The formula built, but is not symlinked into /usr/local
You can try again using `brew link jpeg'
Error: Permission denied - /usr/local/opt/jpeg
resulta em "link brew jpeg" em
Error: Permission denied - /usr/local/opt/jpeg
Aqui está o que meu médico de cerveja lê
$ brew doctor
Warning: "config" scripts exist outside your system or Homebrew directories.
./configure scripts often look for *-config scripts to determine if
software packages are installed, and what additional flags to use when
compiling and linking.
Having additional scripts in your path can confuse software installed via
Homebrew if the config script overrides a system or Homebrew provided
script of the same name. We found the following "config" scripts:
/Library/Frameworks/Python.framework/Versions/2.7/bin/python-config
/Library/Frameworks/Python.framework/Versions/2.7/bin/python2-config
/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7-config
Warning: You have unlinked kegs in your Cellar
Leaving kegs unlinked can lead to build-trouble and cause brews that depend on
those kegs to fail to run properly once built. Run brew link on these:

Esse problema de permissão tornou impossível o uso de cerveja em qualquer coisa e eu realmente aprecio qualquer sugestão.
sudo chown -R $USER:admin /Library/Caches/Homebrew
para me livrar dos meus problemas de permissão.
