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/tanakaakio/.phpbrew/php/php-7.1.3/bin/php-config
