My Yosucker on FreeBSD is broken

Jeffery, the maintainter of YS, and I have been IM'ing
on my problem and he's stumped.

Two days ago YoSucker, running on my 4.11 FreeBSD box,
suddenly stopped working. When I run YoSucker from the
command line I get the following error:

spikework 05:25 PM ~/bin>./yosucker
Using yosucker.conf
SneakySleep is ON!
Login
YoSucker: Abnormal Yahoo Mail behavior (01)! Exiting -
please retry...

Thanks for any ideas. I made no changes to my box that
would cause this error.
