this script below will do exactly that from the port building machine if 
you built them all in one place. (it gathers from 
/var/db/ports/*/options but does not mine the data from 
/var/db/pkg/local.sqlite.) if you'd like to extract options out of your 
installed binary pkg ng's or pkg_og's or dir of .txz's or .tbz's laying 
around somewhere and compare those to the current ports tree, let me 
know. it's slightly more difficult but not terrible.

in case of mail munging and for your convenience this script is posted
