I think the example in the Dancer::Errror documentation is wrong. 
The render method will build the reponse for you, so there is no need to
use Dancer::Response.
Try this:
get '/quux' => sub { err_not_found ( '/quux' ) };
sub err_not_found {
    my $path = shift;
        my $error = Dancer::Error->new(
            code    => 404,
            message => "No such file: $path",
        );
        $error->render;
}
Thanks, this works. 

The man page should be updated to read as follows:

---- quote ----
# taken from send_file:

   use Dancer::Error;

   my $error = Dancer::Error->new(
	   code    => 404,
	   message => "No such file: '$path'"
   );

   $error->render;
----------------

The entry for the "render" method could also more complete,
for example as follows:

----- quote -----
render

Renders a response using Dancer::Response.

The method displays the "message" field and detailed debug
information under the environment setting "show_errors: 1".

Only the error number and the message "runtime error" 
are displayed under the environment setting "show_errors: 0".

Can someone help me find an example of how to use Dancer::Error
and Dancer::Response.
This code (based on man Dancer::Error) gets runtime error
"can't find object method set via package Dancer::Response"
------- code ---
get 'quux' => sub { err_not_found ( 'quux' ) };
sub err_not_found {
   my $path = shift;
       my $error = Dancer::Error->new(
           code => 404,
           content => "No such file: $path",
       );
       Dancer::Response->set($error->render);
}

Thanks,
