1. perl built on different OSes has different logic for @INC population.
  2. Your script will work just fine if you'll place at the very start of it: 
    BEGIN {
  @INC = ('/dir1','/your/special/dir/here');
}
# rest of your code goes here

    I use that approach sometimes in my scripts.
  3. recompiling perl is much easier that it initially seemes to. And lot of platform-specific READMEs help a lot.
addition: BTW what is your OS?
