Does your copy of "r5rs/main.ss" start the same as in SVN?:

 (module main scheme/base
   (require (for-syntax scheme/base)
            (only-in mzscheme transcript-on transcript-off))

The expanded form above doesn't match, so I wonder whether that
particular file isn't up to date on your machine.
