You mean 'port version' (or 'echo $(port version)') :-).

That is right. One should from time-to-time run
sudo port -d selfupdate
I do not have the ports version of GHC installed. So the version of
'port' itself may affect the info about packages, too, it seems.
In addition, one may have to download a new copy from the site. This
happened when I made a new system installation (though restore from
the Time Machine backup worked fine).
Also, updating may break some code - libraries are dynamically linked.
I used this for a compile of Scala (in Ada) which links to the
MacPorts Gtk+ libraries. And now you tricked me to update - let's see
if it breaks.
