Thanks for your suggestions. Unfortunately I get the same error. Here's a SSCCE. Hopefully this helps.

index.mojo: 

#!/usr/bin/perl

use Mojolicious::Lite;
my $logLine;
require './bigFileFullOfSubs.pl';
require './subImWorkingOn.pl';

any '/' => sub {
    my $c = shift;
    $logLine = "";
    subImWorkingOn();
    $c->stash(logLine => $logLine);
    $c->render(template => 'main');
};

app->start;
