Odd; I can't replicate your issue; I see the expected 'oops' error
when I try to replicate your set-up.

It looks like you've compiled your own version of Racket, at least
from the error message.  Let's make sure we can discount one
possibility: can you make sure that Racket's installation went
smoothly?  You can do so with:

    $ raco setup

(This may take a while.)  This should make sure that the Racket
standard library has been compiled.

Once this is done, try running your example again and see if you can
still see that error.
