brew doctor.txt

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 or file an issue; just ignore this. Thanks!

Warning: The filesystem on / appears to be case-sensitive.
The default macOS filesystem is case-insensitive. Please report any apparent problems.

Warning: Your Homebrew's prefix is not /usr/local.
Some of Homebrew's bottles (binary packages) can only be used with the default
prefix (/usr/local).
You will encounter build failures with some formulae.
Please create pull requests instead of asking for help on Homebrew's GitHub,
Discourse, Twitter or IRC. You are responsible for resolving any issues you
experience, as you are running this unsupported configuration.


Warning: /usr/bin occurs before /Users/frizlab/usr/homebrew/bin
This means that system-provided programs will be used instead of those
provided by Homebrew. The following tools exist at both paths:
  smtpd2.7.py
  idle2.7
  idle
  2to3-2.7
  easy_install
  pydoc
  python
  pythonw
  python2.7-config
  irb
  ndisasm
  rake
  rsync
  nasm
  pydoc2.7
  ri
  pythonw2.7
  python-config
  easy_install-2.7
  python2.7
  erb
  rdoc
  smtpd.py
  ruby
  gem

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

Warning: Homebrew's sbin was not found in your PATH but you have installed
formulae that put executables in /Users/frizlab/usr/homebrew/sbin.
Consider setting the PATH for example like so
  echo 'export PATH="/Users/frizlab/usr/homebrew/sbin:$PATH"' >> ~/.bash_profile
