Why do you need to specify this at build time? Under (e.g.) mod_perl Catalyst
will auto-detect it's base URL and Just Handle It, and in the general case
it's trivial to set the base URL from a config.yml

If you need to do more than one of these within the app, you could create

MyApp::Controller::Search1 etc.

with have a sub action_namespace { 'catalyst' } or whatever injected plus
inherit from your base search controller, and use :LocalRegex('^/search/...
to have the base namespace automatically prepended to the regex during
dispatcher setup.
