You can chain your action only to other actions or to the root, not to 
namespaces. The PathPart attribute controls how the path is built 
visibly. There is a :PathPrefix implementation that does what you want 
somewhere in Catalyst's SVN, but I don't know when it is expected to go 
to CPAN.

You can also put the base in the controller base class and configure it 
via your config file or application class:

         PathPart: 'foo/bar/baz'

(untested again, there is an example in the Advent Calendar for 2006)
