Sorry, I was convoluting the issue. To see if BSD.pkg exists, I would 
do in transcript:

put there is a folder "/Library/Receipts/BSD.pkg"

The "which" command; I it suggested for something else. On second 
thought, the "which" command isn't going to help you. If the command, 
e.g. "grep" is on the users path, then you can use shell(). If it's not 
on the user's path, then "which" isn't going to help anyways. Never 
mind!

BTW I'm not 100% sure what the existence of BSD.pkg means. I think it 
means what you are looking for.
