>>> Lint for src/future/FutureProxy.php:


   Error  (PHL1) Unknown Symbol
    Use of unknown function 'qqqqqq'. Common causes are:
    
      - Your libphutil/ is out of date.
        This is the most common cause.
        Update this copy of libphutil: /INSECURE/devtools/libphutil
    
      - Some other library is out of date.
        Update the library this symbol appears in.
    
      - This symbol is misspelled.
        Spell the symbol name correctly.
        Symbol name spelling is case-sensitive.
    
      - This symbol was added recently.
        Run `arc liberate` on the library it was added to.
    
      - This symbol is external. Use `@phutil-external-symbol`.
        Use `grep` to find usage examples of this directive.
    
    *** ALTHOUGH USUALLY EASY TO FIX, THIS IS A SERIOUS ERROR.
    *** THIS ERROR IS YOUR FAULT. YOU MUST RESOLVE IT.
