Troubleshooting a bsdtar installed

[daniel Azuelos]

  Hello,
Recently I encountered a problem during:
	port upgrade Wireshark3
a popur window appeared:
	bsdtar cannot be opened because of a problem.

Nonetheless,
there wasn't any error in the text log,
and the complete build of Wireshark3 succeeded.

I entered:
	type bsdtar
to discover it is the one located in:
	/opt/local/bin/bsdtar
recently installed in my MacPorts tree.

How may I find which package provoqued this install of "bsdtar"?
