module directory has changed (eg. "darwin-2level" vs.
"darwin-thread-multi-2level").
binary packages of perl modules need to be distinguishable between
being built against threaded perl and unthreaded perl, so bump the
PKGREVISION of all perl module packages and introduce
BUILDLINK_RECOMMENDED for perl as perl>=5.8.5nb5 so the correct
dependencies are registered and the binary packages are distinct.

Class::DBI provides a convenient abstraction layer to a database.
It not only provides a simple database to object mapping layer, but can
be used to implement several higher order database functions (triggers,
referential integrity, cascading delete etc.), at the application level,
rather than at the database.
This is particularly useful when using a database which doesn't support
these (such as MySQL), or when you would like your code to be portable
across multiple databases which might implement these things in
different ways.
In short, Class::DBI aims to make it simple to introduce 'best practice'
when dealing with data stored in a relational database.
