title: Git not in PATH for Homebrew on Mac
body: <p>A couple days ago, I ran <code>brew update</code>, trying to update homebrew on my Mac (I use OSX 10.9.5). When I ran this, I got this back </p>

  <p>I also ran brew doctor, to see if anything had changed. This is what came up.</p>

  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: "config" scripts exist outside your system or Homebrew directories.
  `./configure` scripts often look for *-config scripts to determine if
  software packages are installed, and what additional flags to use when
  compiling and linking.
  
  Having additional scripts in your path can confuse software installed via
  Homebrew if the config script overrides a system or Homebrew provided
  script of the same name. We found the following "config" scripts:
    /Users/Robby/anaconda2/bin/curl-config
    /Users/Robby/anaconda2/bin/freetype-config
    /Users/Robby/anaconda2/bin/icu-config
    /Users/Robby/anaconda2/bin/krb5-config
    /Users/Robby/anaconda2/bin/libpng-config
    /Users/Robby/anaconda2/bin/libpng16-config
    /Users/Robby/anaconda2/bin/ncursesw6-config
    /Users/Robby/anaconda2/bin/pcre-config
    /Users/Robby/anaconda2/bin/python-config
    /Users/Robby/anaconda2/bin/python2-config
    /Users/Robby/anaconda2/bin/python2.7-config
    /Users/Robby/anaconda2/bin/xml2-config
    /Users/Robby/anaconda2/bin/xslt-config
  
  Warning: Git could not be found in your PATH.
  Homebrew uses Git for several internal functions, and some formulae use Git
  checkouts instead of stable tarballs. You may want to install Git:
    brew install git
  
  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:
    autoconf
    automake
    bash-completion
    brotli
    c-ares
    cask
    cmake
    cunit
    docbook
    docbook-xsl
    doxygen
    emacs
    fontconfig
    freetype
    gdbm
    geoip
    gmp
    gnutls
    htop
    itstool
    jansson
    jemalloc
    jpeg
    libev
    libevent
    libpng
    libtasn1
    libtool
    libunistring
    nettle
    nmap
    p11-kit
    pcre2
    pkg-config
    python@2
    watch
  
  Warning: You are using macOS 10.9.
  We (and Apple) do not provide support for this old version.
  You may encounter build failures and other breakages.
  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 old version.
  
  
  Warning: Some installed formulae are missing dependencies.
  You should `brew install` the missing dependencies:
    brew install python
  
  Run `brew missing` for more details.

  <p>Any ideas? I'm stumped.</p>
