i can't see a reason why plain rsync on the whole /opt/local would't do just the right thing:
- macports does not use attributes so you do not need to use the special rsync from CarbonCopyCloner
- macports is all of /opt/local, and only that (right??)

rsync -a is the usual "archive" mode but it does not include expensive operations such as deduplicating hardlinks (-H) nor those options that clone special features that make sense only on some filesystems and therefor fail on other filesystems (ACLs, extended attributes...)

therefore, on mac os i use rsync -HESvax --delete, while on linux i use rsync -HAXvax --delete.

cheers
