in reply to Strange File Not Found Error

I'd just like to add that the fragment 
open LABS, "/software/polaris-mfcf/data/local/w.stat" 
   or die "Unable to open file: $!\n";

doesn't do what you expect it to, IIRC. In reality, it's saying something like: 
open LABS, ("/software/polaris-mfcf/data/local/w.stat" 
   or die "Unable to open file: $!\n")

The or operator bonds to the string "/software/...", not to the open command. You'll want to do this instead 
open (LABS, "/software/polaris-mfcf/data/local/w.stat") 
   or die "Unable to open file: $!\n";

Update: Well! I'll be hogtied: "or" != "||". I had always assume that "or" and "and" were just common language equals to their || && counterparts. I didn't know their behaviors where different.

    That's the || operator, not the or operator:
    open FILE, "doesnotexist" or print "or\n";
open FILE, "doesnotexist" || print "|| #1\n";
open(FILE, "doesnotexist") || print "|| #2\n";
