Thanks for confirming the fix.  I've updated the Sandbox document
with the following patch.

Patches/pull-requests to the mailing list for documentation are very
much appreciated, especially for Bundler and maybe other things I don't
use myself.  Lets try to treat the in-source documentation much like a
wiki, except anybody who grabs the source also has the latest up-to-date
docs ready for offline reading (and readable without a web browser :)
