Pycassa should just take your long and do the right thing with it
(packing it into a binary string) before passing it off to thrift.

The system tests in the source (test/system/test_thrift_server.py)
will give you a very good indication of how to do this.  The long is
packed into a string using struct.pack('>p', n), where 'n' is your
long.
