[CentOS] newer smartctl?

If y'all remember the problem I posted a while back, with a 3TB drive for
userspace loosing it on a server, and spitting DRDY errors, but which work
on everything else. Well, enough research, and conversation, and I may
have found the problem: it's a Caviar Green, meant for a desktop, and the
controller in the server has issues, because it uses TLER:

In short, if it hits an error, it can take, in extreme cases, up to two
min to recover; meanwhile, a RAID or HBA controller has hissy fits if it
takes more than 7 or 15 seconds.

I'm ready to test this out; the trouble is, either I d/l a DOS utility, or
I find what, two years ago, was bleeding edge smartmontools; the one with
6.2, 5.39.1-5, does not allows
smartctl -l scterc,70,70 /dev/sdb

So, does anyone know a) what version might include that, and b) where I
can find it? I have no problem building from a tarball, if I need to.
