The port setting only applies if you use the "inbuilt" server in 
Dancer2. This is sometimes useful for one liners or 'app in a script' 
situations and the default port is still 3000. eg:
   perl -E'use Dancer2; get "/" => sub { "Hello" }; dance'

However if you are using one of the PSGI handlers/servers, such as 
plackup (standalone or with Starman, Gazelle, etc.) with the generated 
bin/app.psgi, those servers are responsible for the port binding. In 
this case you need to pass the port as an argument to that server as you 
noted above.

If you think the docs could be clearer about this, we'd really 
appreciate a doc patch!

Hope that helps,
