I'll see what I can get done tonight.

On all the previous installs I've done, they've been stock standard
installs. No patching has been necessary.
That's the really odd thing about it all. I would have thought that I
would have seen this problem earlier.
On this machine it will only work if I patch the FreeTDS driver.
I've put the patched version up on GitHub http://github.com/dparnell/freetds/tree/master
if anybody is interested.
