[racket] sandbox error

Hi. I'm trying to use a racket sandbox to safely evaluate some
scribble code, but I'm having trouble setting up the sandbox in the
first place. The following produces an error on my system:

(make-evaluator 'racket/base #:requires '(scribble/manual scribble/racket))

The error is:

../../../../../../../usr/share/racket/collects/racket/private/so-search.rkt:37:20:
file-exists?: `exists' access denied for /usr/lib/libcrypto

I'm running Racket 6.1.1 on Arch Linux x86_64. The exact same code
seems to work correctly for Michael Ballantyne with Racket 6.1 on a
Mac. Am I doing something wrong? Is there a reason Scribble needs
libcrypto? Is this a bug I should report? I truly don't know what's
going on.

Please help,
Lucas
