FWIW, I wrote (with some colleagues) a database migration system  
called bering.  I mention it because it has an ant task, so you can  
use it with buildr with no changes.

It's more specifically a port of rails' ActiveRecord migrations, so  
the implementation is a bit different from Carbon Five's.  In  
particular, it uses a groovy DSL backed by a hibernate-like dialect  
system (instead of plain SQL scripts) to support multiple databases.   
(It was developed for use with a suite of clinical research  
applications which support either PostgreSQL or Oracle.)

Deployment-wise, bering includes a ServletContextListener that can  
automatically apply new migrations on application startup.

End plug.
