Is there an easy way to determine if a given path is on a network drive vs a local drive?

The environment is OS X (BSD), but I am looking for the Perl Unix way of doing it. I know how to do it on Windows.

I have looked at stat, and there is the method of looking at the device number like this: 
if (-x $file && (($d) = stat(_)) && $d < 0) {
    print "$file is executable NFS file\n";
}

I am looking for a more general way to detect if the file is on a network device, and the type of network if so. Respectfully submitted with thanks...
