Minor issues with the information returned by arc lint. In arcanist/src/lint/linter/ArcanistCpplintLinter.php:

public function getInstallInstructions() {
  return pht(
    'Install cpplint.py using `%s`.',
    'wget http://google-styleguide.googlecode.com'.
    '/svn/trunk/cpplint/cpplint.py');
}

This is out of date; following the instructions will return a 404.

Cpplint is now located at https://github.com/google/styleguide under cpplint
