When `graphics-posn-less@' imports `mred^', it declares that the
corresponding unit must be executed before `graphics-posn-less@'
itself.

The solution is to reverse the order of units in the `link' clause on
line 17 of "big-draw.ss".

When someone can tell me what the error message means, I'll start
looking into it. (I am wondering whether it's related to the backdoor
into drscheme that hangman opens up.)

I don't know what it means, but it happens in #lang scheme, too:

#lang scheme
(require htdp/hangman)
