Estou tentando instalar a estrutura Metasploit (sem importância) e o bundler está tentando instalar o sqlite3, que é onde falha constantemente. O sqlite3 está instalado (a execução do sqlite3 na linha de comando me leva ao ambiente) e é vinculado usandobrew link sqlite3 (e adicionando o --force, por algum motivo), masbundler install falha sempre com este erro:

sudo gem install sqlite3
Building native extensions.  This could take a while...
ERROR:  Error installing sqlite3:

Error: Running Homebrew as root is extremely dangerous and no longer supported.
As Homebrew does not drop privileges on installation you would be giving all
build scripts full access to your system.

sqlite3 is missing. Try 'brew install sqlite3',
'yum install sqlite-devel' or 'apt-get install libsqlite3-dev'
and check your shared library search path (the
location where your sqlite3 shared library is located).
