I'm afraid your testing the wrong variable there. Instead of $!, which is what is used when something goes wrong in perl, you want $? which is the return status of system().
So it seems that the error concerned occured earlier on in your program, which sounds like the result of mishandling your files (it's errno 9 if that's of any help). Then there's also the fact that your system() call is returning a non-zero return code which should probably be of concern.
