mSQL v2.0 beta 5 and above make changes to the AVL index format of your
databases.  In order to preserve your existing data, you must:
	- use msqldump to dump all your databases
	- install beta 5 or above
	- use msqladmin to drop and then create each of your databases
	- use msql to reload your data

If you understand the consequences of this upgrade, please re-build this
port with the environment variable OVERWRITE_DB defined.
