That solved it.

A minor difference (from Dancer 1):
In the "index.tt" template, there's a sidebar which contains:
=====
 <h3>Your application's environment</h3>
       <ul>
                <li>Location: <code>/home/gordon/projects/dancer_test/MyFirstApp</code></li>
                <li>Template engine: <code><% settings.template %></code></li>
                <li>Logger: <code><% settings.logger %></code></li>
                <li>Environment: <code><% settings.environment %></code></li>
            </ul>
=====

With Dancer 1, the output is :
===
Your application's environment
    Location: /home/gordon/projects/dancer_test/MyFirstApp
    Template engine: simple
    Logger: console
    Environment: development
===

With Dancer 2, the output is:
===
Your application's environment

    Location: /home/gordon/projects/dancer_test/MyFirstApp
    Template engine: Dancer::Template::Toolkit=HASH(0x188dcb8)
    Logger: Dancer::Logger::Console=HASH(0x1602758)
    Environment:
===

That is - with the "HASH(0x188dcb8)" part of the engine & logger objects.
Also - it seems "environment" is not set, but perhaps that's another (updated) configuration option that I'm missing.

Yes, it works with Dancer1.

Here's how to reproduce:
=========

##
## Create a new application
##
$ dancer -a d2test4
[...]
$ cd d2test4/

##
## Add a "prefix" statement
##
$ sed -i '6iprefix "/testme";' lib/d2test4.pm 

##
## show the updated application
##
$ cat lib/d2test4.pm 
package d2test4;
use Dancer ':syntax';

our $VERSION = '0.1';

prefix "/testme";
get '/' => sub {
    template 'index';
};

true;


##
## Run with Dancer 1

I did not change the "config.yml" file with the correct template syntax, but I assume it is not relevant for this behavior.
