     Actually, the issue is only whether you have 64-bit MySQL client 
libraries for C to which MySQLdb can link.  Those are called
"MySQL Connector/C", and here are the download pages for them.

The actual database can (and usually should be) the 64-bit executable, 
while the libraries can be 32 or 64 bit. They communicate over a socket,
and don't even need to be on the same machine.

Unfortunately, the whole MySQLdb/Python/Connector/C versioning
setup is a mess.  See:
