problems with postfix

Testing it on postfix  2.0.16 I'm following the docs and have
in my master.cf:

# SPF handler
policy  unix    -       n       n       -       -       spawn
user=nobody argv=/usr/bin/perl      /usr/lib/postfix/spf-policy.pl

And in my main.cf:

smtpd_recipient_restrictions =
  permit_mynetworks,
  permit_sasl_authenticated,
  reject_unauth_destination
  check_policy_service unix:private/policy

and optionally putting in:

smtpd_policy_service_endpoint = unix:private/policy

before smtpd_recipient_restrictions (either way, same problem)

When I connect to the server smtpd is throttling:

Mar  4 13:53:10 spaz postfix/smtpd[23313]: fatal: dict_unix_open: unknown
map name: private/policy

Mar  4 13:53:11 spaz postfix/master[8138]: warning: process
/usr/lib/postfix/smtpd pid 23313 exit status 1

Mar  4 13:53:11 spaz postfix/master[8138]: warning:
/usr/lib/postfix/smtpd: bad command startup -- throttling

Any ideas?
