setup tutorial with local provider - never goes beyond pending

[Dan Kortschak]

I have installed juju according to the instructions at [1] for a local
machine running 12.04 (with the recommended raring 3.8 kernel).

I have then run through the micro tutorial/demo at [2] - including
turning of ufw. Everything seems to work except that the status does not
go beyond pending:

$ sudo juju bootstrap
$ juju deploy mysql
$ juju deploy wordpress
$ juju add-relation wordpress mysql
$ juju expose wordpress
$ juju status
environment: local
machines:
  "0":
    agent-state: started
    agent-version: 1.14.1.1
    dns-name: 10.0.3.1
    instance-id: localhost
    series: precise
  "1":
    instance-id: pending
    series: precise
  "2":
    instance-id: pending
    series: precise
services:
  mysql:
    charm: cs:precise/mysql-27
    exposed: false
    relations:
      cluster:
      - mysql
      db:
      - wordpress
    units:
      mysql/0:
        agent-state: pending
        machine: "1"
  wordpress:
    charm: cs:precise/wordpress-19
    exposed: true
    relations:
      db:
      - mysql
      loadbalancer:
      - wordpress
    units:
      wordpress/0:
        agent-state: pending
        machine: "2"

Is this what is expected? If it is, where do I get see the exposed
service/public address? If not, what is going on?

thanks
Dan
