Please don't crosspost.
I don't think this is a topic for -current, so I've removed it.

Your attempt to setuid(0) failed.

Your attempt to run that perl script failed.

Well, since your attempt to setuid(0) failed, `new.pl` is not being
execve()'d as root. Therefore, the permissions on the `new.pl` file are
such that it can't be read or executed by the user/process.
