open(OUT,">>$sql_file");
  print OUT localtime().' ^ '.$pid.' ^ '.$_[0]."\n";
  close(OUT);

That sounds like the open has failed. Did you define $sql_file variable? And you should do error checking after open:
open OUT, ">>$sql_file" or die "Can not open $sql_file";

I define variables in one bit of code then use them in another 'required' file in a rather obscure but functional way.

Sounds like bad programming practise to me. Take a look at the following node on better programming practise:

  • Perl Programming guidelines/rules

    A cleaner approach I would take is to build a hash of variables, and pass the reference to the hash to the constructor / initializer of your module -
    use strict;
use warnings;
use MyModule;

my %vars = (
  'foo' => 'bar',
  'date' => '20040203',
  'name' => 'roger',
  ...
);

my $mymodule = MyModule->new(\%vars);

    And then in your module you refer to the variables by name.
