Installed the freetds rpms from centos-extras, also tried the ones in 
rpmforge
http://mirror.centos.org/centos/5/extras/x86_64/RPMS/freetds-0.64-11.el5.centos.x86_64.rpm
http://mirror.centos.org/centos/5/extras/x86_64/RPMS/freetds-devel-0.64-11.el5.centos.x86_64.rpm

Compiled python-sybase-0.39 by hand, and also via rpm.

This spec file modified to compile on x86_64:

  mkdir -p $PYTHONPATH
  export SYBASE="/usr"

Both the source version and the rpm are built basically the same way, 
and the final result after installation is something like:

# python

As per this thread:
http://mlblog.osdir.com/python.sybase/2004-03/

Something may be going wrong in linking, as the sybasect.so doesn't seem 
to be linked to the sybase libraries.

$ ldd 
~/.python-eggs/python_sybase-0.39-py2.4-linux-x86_64.egg-tmp/sybasect.so
         libpthread.so.0 => /lib64/libpthread.so.0 (0x00002aaaaacdf000)
         libc.so.6 => /lib64/libc.so.6 (0x00002aaaaaef9000)
         /lib64/ld-linux-x86-64.so.2 (0x0000555555554000)

Suggestions, comments, fixes, would all be useful.
