Hallo Jorge,

Cannot say the exact raeson, but i left out the 'or die' and it works.
#!/usr/bin/perl

$args = "perl -i.orig -pe \'s!/home/ftp!/!g\' /etc/passwd";
system($args);

Maybe some native english speaker has a better understanding of this
part of perlrun.pod:

       -p   causes Perl to assume the following loop around your
            program, which makes it iterate over filename argu­
            ments somewhat like sed:

              LINE:
                while (<>) {
                    ...             # your program goes here
                } continue {
                    print or die "-p destination: $!\n";
                }

            If a file named by an argument cannot be opened for
            some reason, Perl warns you about it, and moves on to
            the next file.  Note that the lines are printed auto­
            matically.  An error occurring during printing is
            treated as fatal.  To suppress printing use the -n
            switch.  A -p overrides a -n switch.

            "BEGIN" and "END" blocks may be used to capture con­
            trol before or after the implicit loop, just as in
            awk.
