8.4: move to pkgng - "No valid repository found."

[Mike.]

I'm running FreeBSD 8.4.  I want to move to the new package system
(I've been using it on 10.0, and I like it a lot).

Soooo... here's what I did.

- install /usr/ports/ports-mgmt/pkg

- followed these instructions:
   - switch to pkgng:
       1) Add WITHOUT_PKGNG to /etc/make.conf
       2) Install ports-mgmt/pkg
       3) Convert your package database by running pkg2ng
       4) Remove WITHOUT_PKGNG from /etc/make.conf

(btw,(1) above, I used "WITHOUT_PKGNG=YES" )


- pkg info 
	I see the list of packages installed

- pkg update
	I see

		Updating repository catalogue
		No valid repository found.



What did I do incorrectly?  Or, more importantly, how do I get back
on track?

Thanks.
