Start with package.json and the failing setup in test/index.js around line 152, then run the reported dependency substitution followed by make prepush. Check how restify 5.x exposes the accept parser and identify the compatibility change needed for restify-clients. Done means the restify-client tests and make prepush pass with restify 5.x.
