I was saying you could possibly simplify the code to

pre-activate {
    delete ${frameworks_dir}/R.framework
}

if you're sure that no other port installs files there.

You're currently using glob, not fs-traverse. glob is a standard Tcl command that finds matching items in one directory. It doesn't attempt to look into its subdirectories.

fs-traverse is a MacPorts-specific addition to Tcl which traverses a directory's subdirectories. It's like the "find" command on the command line.
