Ports, pkg's confusion on upgrades...

[Karl Pielorz]

By letting 'pkg upgrade' complete, then running 'pkg info --all -d' I was 
able to find out what package upgrade now requires an additional package 
"to be INSTALLED".

(In our case memcached-1.4.20_2 pkg now requires cyrus-sasl-2.1.26_8 - 
where as it didn't before).

I still can't figure out how to get pkg upgrade to reveal *why* it needs to 
install this, *before* it does it (i.e. only by letting it do it, then 
running 'pkg info --all -d' did it then show memcached having a dependency 
on cyrus - where as the older version of memcached didn't.
