Racke and Gabor, Thank you very much for the replies.

$upload_dir was being set just before the get route -- which I realize is
not correct so I have now put it in the post route like below and the
results are the same.

Both machines run perl (v5.20.2).

On the development machine I start Dancer2 with: plackup -r bin/app.psgi

On the production machine: service starman start; which uses argument:
'/home/starman/Almslete/bin/app.psgi (see starman.pl below) Gabor I
followed your excellent tutorial: http://perlmaven.com/getting-started-with-
perl-dancer-on-digital-ocean

post '/upload' => sub {

my $upload_route = '/upload';
my $upload_dir = 'public/profile_pics';

    my $user_id = session 'UID';
    my $d_filename = 'user_' . $user_id . '.jpg';

    my $file = request->upload('file');
        my $tmpname = $file->tempname;
        debug "File Size: ", $file->size;
        debug "file: ", $file->filename;
        debug "tmpname: ", $file->tempname,
        my $destination = $upload_dir . '/' . $d_filename;
        debug "Destination: $destination\n";
        my ($crslt) = $file->copy_to($destination) || warn $!;
        #unlink $tmpname if -e $tmpname;

        debug "crslt: ", $crslt;

        template 'upload';

    redirect '/playerdash';
};

/home/starman/starman.pl

#!/usr/bin/perl

use warnings;
use strict;
use Daemon::Control;

use Cwd qw(abs_path);

Daemon::Control->new(
    {
    name      => "Starman",
    lsb_start => '$syslog $remote_fs',
    lsb_stop  => '$syslog',
    lsb_sdesc => 'Starman Short',
    lsb_desc  => 'Starman controls the web sites.',
    path      => abs_path($0),

    #program      => 'plackup -E deployment -s Starman',
    program      => '/usr/local/bin/starman',
    program_args => [ '--workers', '3',
'/home/starman/Almslete/bin/app.psgi' ],

    #plackup -E deployment -s Starman --workers=10 -p 5001 -a
bin/app.psgipl
    user  => 'starman',
    group => 'starman',

    pid_file    => '/tmp/starman.pid',
    stderr_file => '/tmp/starman.err',
    stdout_file => '/tmp/starman.out',

    fork => 2,

    }
    )->run;


Thanks again for the help.
