Error on virginal install rendering scribble w/ sandbox

[zenspider]

after nuking prefs and ~/Library/Racket open the following in drracket:

#lang scribble/manual
@(require racket/sandbox)
@(define evaluator (make-evaluator 'racket))
@(define typed/evaluator (make-evaluator 'typed/racket))

Render to get the following error

 ../../MyApplications/dev/lisp/Racket/collects/pkg/private/lock.rkt:26:0: directory-exists?: `exists' access denied for /MyApplications/dev/lisp/Racket/share/pkgs

With ~/Library/Racket I was getting errors about not having read access for a pkgs lock file (it existed and I had read access)... But out of the box, this thing should work.
