I second this technique. It's the best way I have found.

Recently (pkgsrc-2007Q1) I have found that, after pkg_comp is done and
everything looks good in the chroot environment, pkg_chk with the `-b'
option seems to work well; meaning you don't have to remove everything
(or anything). Usually if anything is missing, they are reported by
pkg_chk and you can just pkg_add them from the newly built binaries.
