If you don't want to make your libraries into modules (which tends to imply object oriented methodology, etc.) you might instead put them into packages. If your familiar with C++, this is the same idea as putting them into a unique namespace.

Here's a real simple example:

This is file MySub1.pm: 

package MySub1;

use MySub2;

sub AAA {
  my $x = MySub2::DDD();
  return "AAA : $x";
}

sub BBB {
  return "BBB";
}

1;

This is file MySub2.pm: 

package MySub2;

use MySub1;

sub CCC {
  my $x = MySub1::BBB();
  return "CCC : $x";
}

sub DDD {
  return "DDD";
}

1;

[download]

This is file mytest.pl: 

use strict;

use MySub1;
use MySub2;

print MySub1::AAA(), "\n";
print MySub1::BBB(), "\n";
print MySub2::CCC(), "\n";
print MySub2::DDD(), "\n";

Summary: so you have MySub1, a package that contains subroutines, some of which call other subroutines in MySub2; and MySub2 contains subroutines that call subroutines in MySub1. The actual perl script uses subroutines from each of these packages.
