This was the result of the first attempt to upgrade the port from 2.7.2_0 tp 2.7.2_1 due to [82967] trunk/dports ... (I have python27 installed as a dependency of maildrop). 

So should I be doing a "port clean" everytime before upgrading any port?

The iMac is otherwise stable, it runs 24/7 and doesn't hang while running memory intensive or cpu intensive or disk intensive Mac programs. This just happens to be the first time I've managed to make a copy of the main.log before it vanishes.
