v2 will probably work fine, but you should install darwinports. Then it's just one command to install sqlite3: "sudo port install sqlite3"
http://sqlite3.darwinports.com/Wiki says "In August 2000, version 1.0 of SQLite was released, based on gdbm (GNU Database Manager). SQLite 2.0 replaced gdbm with a custom B-tree implementation, adding support for transactions. SQLite 3.0, partially funded by America Online, added internationalization, manifest typing, and other major improvements."
