[racket-dev] Strange module mismatch

Is the DrRacket option "populate compiled/ directories" enabled or
disabled?  If it is enabled, disable it and try again.  I get this
kind of behavior with planet development links sometimes; see PR
10685.  Of course, these problems may not be directly related even if
this option does fix your program.
