"make package" vs "pkg create"

[Joshua Isom]

I tried making a build jail, not with pourdriere or tinderbox.  I just 
went to the ports and ran `make -DBATCH package-recursive clean` to get 
packages created.  I ran `pkg add *` in the packages/All directory, but 
all failed because of MANIFEST missing.  I'm guessing this is a bug in 
the .mk files, since I do have WITH_PKGNG set.  Is this a known problem 
or is there supposed to be a different way to do it?  Am I just supposed 
to use pourdriere or the source to keep my ports up to date until all 
the packages are rebuilt on freebsd.org?
