Some gems can't be used with the old version of ruby that ships on the latest OSX. Homebrew can install an alternate "system" ruby with brew install ruby to $HOMEBREW_PREFIX/opt/ruby/bin. It would be convenient to provide a way to detect or select that alternate ruby and prefer it over the system ruby at /usr/bin/ruby.
