[CentOS] CentOS 6.7->6.8, ssh-add issue

Folks,

   I am perplexed. I updated my workstation at work Wed before I left,
from 6.7 to 6.8. Then, yesterday, I went to use ssh-add -s
libcoolkeypk11.so, which I've done many times before to add the certs
from my PIV card... and 100% of the time if fails, letting me
SSH_AGENT_FAILURE, cannot add card.

   Now, using a script called sccr, which uses my public and private key
to generate a one-time password (we use the to sudo to root), works
with no problem. I used my card to go into the data center this
morning, which also reads my card, and had no problem. I've tried eval
$(ssh-agent) to start a new instance. Nothing works.

   Also, pklogin-finder finds the cards, asks for my PIN< and it works.

   Clues for the poor?
