upgrading MacPorts after updating from 10.6 to 10.9 - missing gnutar?

`sudo port selfupdate` will only fix this, if the current version of base is actually outdated, i.e. if you had 2.2.0 installed before upgrading to Mavericks. If you already had 2.2.1 installed before the OS upgrade, selfupdate will not reconfigure/rebuild and this will not work. That's why I suggested using `sudo port -f selfupdate`, which skips the version check and forces the rebuild, but I now realize this might not have triggered a re-configure either.

I guess the selfupdate action should check whether current base has been built on an older OS and trigger the rebuild if it was. I know we recently added a field for the OS version when base was built, but I'm not sure we already trigger selfupdate on OS version mismatch.
