What you probably did is make delete-old-libs.
This deletes the old 8.x libs that where used by your ports.
What you need to do is rebuild all your ports.

That way they get linked to the proper libs again.

The next time when you go from one major to another major number eg from 
7 to 8 or from 8 to 9 and so on, is to do the make delete-old-libs step 
Then after upgrading, rebuild all your ports, they still work with the 
old libs.
Once the ports are rebuild against the newer libs then do the make 
delete-old-libs step.

This is not nessacery when going from a minor number to amother minor 
number. eg from 8.1 to 8.2 and so on.

Hope this helps.
