I think you actually need the functions in this list from the GYP file or this
will do nothing:
                     'brlapi_getHandleSize',
                     'brlapi_error_location',
                     'brlapi_strerror',
                     'brlapi__acceptKeys',
                     'brlapi__openConnection',
                     'brlapi__closeConnection',
                     'brlapi__getDisplaySize',
                     'brlapi__enterTtyModeWithPath',
                     'brlapi__leaveTtyMode',
                     'brlapi__writeDots',
                     'brlapi__readKey',

   }
 }
