Try uninstalling R before trying again. When activating, it may be using the pre-activate block in the portfile that was current at the time the archive was built, rather than the pre-activate block in the latest version of the portfile.

Try running port with the debug (-d) flag.

Try using ui_info or ui_debug instead of ui_warn.

Look at the value you're setting filepath to. You're prepending ${prefix} though it should already begin with ${prefix}, so now you've got a double prefix.

Don't hardcode /Library/Frameworks; use ${frameworks_dir} (unless the port previously used a hardcoded /Library/Frameworks when installing these files).
