portupgrade fu... AKA there has to be a better way

[Doug Poland]

Hello,

I'm upgrading a server from 6.4 to 7.1 and am going through the relative
pain of re-compiling all the ports.  It's not as easy "portupgrade -af"
because of all the special handling instructions of many ports.

I have not found an "easy" way to keep track of the ports that need to
be forcibly updated but have not undergone a version change.  Because I
approach the upgrade in steps, I need to run portupgrade several times
but want to exclude stuff already compiled under 7.x.


What I need is a command like:

   # portupgrade -af -x "already compiled on 7"


Suggestions, comments, rebukes welcome.
