building python-sybase on OS X 10.3

To build python-sybase on Mac OS X 10.3:

1. Install all three kits from the Sybase-provided dmg

2. Set your SYBASE environment variable

3. 'python setup.py build' ... this will compile all the files, but you 
will blow up at link time on a pile of undefined symbols

4. Copy the gcc command that blew up to the clipboard and re-paste it 
to your command line.  Navigate to right before '-framework Python' and 
add '-framework SybaseOpenClient -framework CoreFoundation'.  Then 
press return to re-run the link operation.

5. 'python setup.py install' and you should be in working order.  Run 
the examples to test.
