A quick look on CPAN turns up File::Same and File::is
File::Same doesn't check, whether two pathes name the same file, but whether two pathes point to (possibly different) files, having the same content.

File::is tries to verify the identity of the files, but only by inode number, which is (as we have learned from ambrus is not even correct on Unix, and does not work at all on Windows :-(
