<div>Hi,</div><div><br></div><div>Recently (1-2 weeks?) GIT HEAD stopped working for me with the following error.  This happens in DrRacket when I attempt to use the REPL (hit the Run button, get the prompt, enter anything &lt;rtn&gt;, and BORK!! as below).  Everything else in DrRacket is flawless, editing, TypedRacket performance, check syntax etc.</div>
