Installing on Mac OS X w/ Sybase 12.5.0.2

Hello,

I have just installed Sybase ASE 12.5.0.2 on my MacOS X 10.2.4 box, and have
no problems building the sybase module (with
SYBASE=/Applications/Sybase/System/OCS-12_5), but when I try to use the
module, I get this error --

Python 2.3a1 (#1, Jan 26 2003, 21:54:53)
[GCC 3.1 20020420 (prerelease)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import Sybase
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "Sybase.py", line 20, in ?
    from sybasect import *
ImportError: Failure linking new module: /usr/local/lib/libct.dylib: dyld:
python version mismatch for library: /usr/local/lib/libct.dylib
(compatibility version of user: 12.5.0 greater than library's version:
2.0.0)

-- any thoughts on how I can correct this problem?

Thanks,
David.
