Hmmm, you've got a point. Don't think I ever ran into it but I'll remember (off late on 10.6 it was too tempting to use -p).

Things started out fine, but somehow I found myself with a 64bit-only libiconv (despite the fact that the database told me I had the universal variant, as requested), which of course gave problems. Couldn't figure out how to force-reinstall the port, so I uninstalled it, and then of course gnutar no longer worked. Long story short, I'm following the migration guide now.
I presume the tcl "restore" script restores all ports in the input list, and not only the most recent versions of the listed ports, so I'd have to uninstall all inactive ports before generating the list if I don't want to have to prune it by hand?
