problem with python-sybase 0.37 and OCS 15.0

We have been running 0.36 against OCS 12.5 libraries on Fedora for a 
while with no problem, but only with a 32 bit configuration.  We finally 
got 64 bit libraries via a new Sybase OCS 15.0 package , and once I 
patched up the setup.py to use the correct libraries, everything built 
out and I was able to do an "import Sybase".

However, if I actually try to make a connection to the db, I get a 
really weird error that I don't understand (obviously this works with 
the old setup):

test code:

import os
os.putenv('SYBASE','/usr/sybase')
import Sybase
user = 'hitech'
password = 'hitech'
conn = Sybase.connect('DBSERVER',user,password,auto_commit=1)

error:

Anybody seen anything like this?

Thanks,
