portupgrade configuration

[Robin Becker]

I've been using the cvsup/portsdb/portupgrade mantra and have found 
problems recently with subversion. Basically I needed to do

make deinstall
SVNREPOS=/svn SVNGROUP=rptdev WITH_APACHE2_APR=1 make install

by hand as portupgrade didn't seem to know what settings it should use.

Is there a way to list all of my exceptional port settings? Can I make 
these available to portupgrade automatically somehow?
