Sam2, it seemed neither you, nor anybody else in CR Land, were interested, or able, to help out.
So a real person in the real world did. (Thanks!)
And here it is:
Avira d’Eretz Yisrael machkim.
It’s in B”B.
I was going to leave it at that.
But since B”B is so long, I’m offering a bit of help.
It’s in the 9th perek.
