Will pkg-static install an old version of pkg?

One option might be to check if the old version of pkg is in
/var/cache/pkg, then maybe pkg-static could be used to 
reinstall the old version.

Alternatively, if ports are installed, one could rebuild the
old version of pkg from the port. Or even download the 
appropriate old ports tree to be able to build the old pkg.
That would also enable building an old(?) version of trafshow.

But I agree with others that the right answer is to upgrade the
system. Running old systems facing the Internet is a bad idea.
