[Bro] Couple script questions

[James Lay]

Stemming from the previous posting, I'd like to try the below scripts:

https://github.com/sethhall/ssn-exposure
https://github.com/sethhall/credit-card-exposure

 From the ssn-exposure I see the install info:

cd <prefix>/share/bro/site/
git clone git://github.com/sethhall/ssn-exposure.git
echo "@load ssn-exposure" >> local.bro

I'm assuming this is the same for credit-card-exposure as well?  Also, 
I see:

Detect US Social Security Numbers with Bro. This script only works with 
Bro 2.1.

Is this still the case?  I'm running 2.2 beta...thanks for any 
assistance.
