[maemo-developers] Having trouble installing the scratchbox development environment.

[From: Hendrik Boom]

I'm following the instructions in
  http://inz.fi/blog/2007/10/22/multi-target-development-for-maemo/
as advised by Graham Cobb, and have run into a snag.

When I get to the point of creating the bora rootstrap, it tells me:

hendrik at lovesong:~$ sb-conf rs mistral-armel /scratchbox/packages/mistral-armel-rootstrap.tgz
ERROR: You don't have a Scratchbox user account!
hendrik at lovesong:~$ 

Now doing
 adduser hendrik sbox 
was easy, but it didn't help.  Evidently something else is also required.

One relevant point: The instructions said, "when it asks for users to add 
to scratchbox, just choose your user (and whomever might want to do 
scratchbox development on the box)."  But it has never asked for users.

How do I fix this up after the fact?
