[racket] Dr Racket error OS X Lion

A little more news:

  It turns out that the fix that I thought took care of the problem
(removal of the (set! todo '() line as below) was not right. I have
now pushed a second attempt at a fix for the problem. I'm not able to
reproduce the problem anymore on my machine, anyways.

If you have the wherewithal to give the git version a try (or the
nightly build sometime tomorrow (assuming that the date says at least
Monday morning when you look at it)), please let me know if you can
make the problem come back.

Thanks,
Robby
