Caution should be exercised when deleting /opt/local.
Examples: the user may have valuable database files in /opt/local/var/db/mysql5 or conf files in /opt/local/etc.

I would suggest you first move /opt/local out of the way; then after you have the current MacPorts installed and previous functionality restored you can delete the old dir.

To move old prefix out of the way.
$ sudo mv /opt/local /opt/local-20120111
