I did try a few more upgrades for specific named ports rather than  
"installed" ... but they all errored in much the same way. And so I  
then started on the roll-back to 10.5.8 - TimeMachine did a good job,  
although Mail insisted on rebuilding all my mailboxes (30 mins for 1  
million emails).

my current "port installed" has amongst others ...

   gawk @3.1.7_0 (active)
   grep @2.5.4_0 (active)
   gsed @4.2.1_0 (active)

But gawk and gsed only got there by being dependents of something  
else. grep I think I installed. Is there any way of determining which  
ports were user-installed and which were only dependent-installed?
