Ok - I'm not sure if this is worthy of adding to the PR load so I'll
just post it to the list and if someone has time, great, if not,
that's fine too.

The port is security/wipe and the only difference between 2.3.0 and
2.3.1 is a Makefile tweak regarding uninstallation (since we use
pkg-plist, not the supplied target, it doesn't matter).
