First of all, you can easily install Algorithm::Diff yourself, see Yes, even you can use CPAN.

Second, if you read diff, you will find that the exit status for identical files is 0 and otherwise nonzero. If you read system, you will find that it returns the exit status of the program. So you might just want to use that.
