Your immediate problem is that DBI::connect() returns a DBI::db object, not a DBI object, so your subclass does not inherit from the right class.

You don't need inheritance for this to work though. Take out all of the @ISA code and change the last few lines of new() to:

# Connect
return DBI->connect( $datasource, $dbuser, $dbpass );

If you do that, the caching will still work as long as all of your code calls the instance() method. (If it were my code, I would rename new() to connect() or something similar to make it more clear that this is a singleton factory.)
