$ brew doctor
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: You have HOMEBREW_BUILD_FROM_SOURCE set. This environment variable is
intended for use by Homebrew developers. If you are encountering errors,
please try unsetting this. Please do not file issues if you encounter
errors when using this environment variable.

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:
  rust

Warning: You have uncommitted modifications to Homebrew
If this is a surprise to you, then you should stash these modifications.
Stashing returns Homebrew to a pristine state but can be undone
should you later need to do so for some reason.
  cd /home/buck/prefix/brew/Library && git stash && git clean -d -f
