It's quite possible the Inappropriate ioctl for device is a red herring. $! will only be set if a call to the OS fails. Since a program run by system returning a nonzero exit status isn't considered a failed OS call, $! may contain gibberish. You may find more useful information by looking at $?, and/or any error output from the program you're running.
