Any port.

Note that the registry only contains files and symlinks, not directories, which some of the items you're globbing are. If you're sure that no port other than R should be installing anything in ${frameworks_dir}/R.framework, but rkward or some other port previously did without registering that, you could just unconditionally delete that pre-activate. Or you could fs-traverse that directory and just delete things not registered to any port.
