If you weren't getting the file opened, it shouldn't exist, even at zero bytes. You might want to test the return of the open() call and print any errors to make sure. 
open my $output, '>', $localFile
    || die "Cannot write to $localfile: $!\n";

What's the size of the uploaded file? Are you sure it's longer than zero bytes in the temp directory after the upload? Perhaps it's a permissions issue with the upload. Why are you using binmode() on the output but not the input filehandle? You have no counter to see how may times you get lines in your while loop nor any test of the length of the lines. How can you be sure you're not writing exactly what there is to write?
