Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry and just ignore them. Thanks!

Warning: Your XQuartz (2.7.5) is outdated.
Please install XQuartz 2.7.9 (or delete the current version).
XQuartz can be updated using Homebrew-Cask by running
  brew cask reinstall xquartz

Warning: Python is installed at /Library/Frameworks/Python.framework

Homebrew only supports building against the System-provided Python or a
brewed Python. In particular, Pythons installed to /Library can interfere
with other software installs.

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:
  python3

Warning: /usr/bin occurs before /usr/local/bin
This means that system-provided programs will be used instead of those
provided by Homebrew. The following tools exist at both paths:
  2to3
  2to3-2.7
  easy_install
  easy_install-2.7
  idle
  idle2.7
  pydoc
  pydoc2.7
  python
  python-config
  python2.7
  python2.7-config
  pythonw
  pythonw2.7
  smtpd.py
  smtpd2.7.py
  tclsh
  wish

Consider setting your PATH so that /usr/local/bin
occurs before /usr/bin. Here is a one-liner:
  echo 'export PATH="/usr/local/bin:$PATH"' >> ~/.bash_profile

Warning: Broken symlinks were found. Remove them with `brew prune`:
  /usr/local/lib/node_modules/node-red/node_modules/.bin/serialportlist
  /usr/local/lib/node_modules/node-red/node_modules/.bin/serialportterm
  /usr/local/opt/bash
  /usr/local/opt/curl
  /usr/local/opt/hub
  /usr/local/opt/mtr
