Looks like you want to read this:

POLA is an ideal, it may be necessary to violate POLA for example for 
security reasons, and you may have system upgrades that will require 
rebuild of ports too - recently a bug in openssl required a rebuild of 
world - and I assume any ports built against the base' openssl.

I don't understand your concern, if you upgrade the base system wouldn't 
it be time to check your ports too? If you insist just don't update your 
ports tree, that should keep it working with the same versions of ports 
although you may have to rebuild individual ports.

I find it easier to adapt continuously to small astonishments :)
