I think you're looking for sysmerge options -d and -p.

If I understand correctly that you try to achive, when I'll do somethign
like that:

1. pkg_info -mz -- to get list of installed packages
2. sysmerge -d -- to get changes in system's config files
3. sysmerge -d -p -- to get changes in port's config files

with all of this in new machine:

1. pkg_add $(cat list-with-packages)
2. apply diff from previous (2)
3. apply diff from previous (3)
