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.
