Hi monks,i am quite new in perl programming (only 2 weeks learning)and i have a question about my script, the idea is that the script prints some things about a choosen filesystem and gives the avalible space, the used space, the type, etc.

All sounds good, but when I run my script it returns a error ("Illegal division by zero at analizer (16-1-17).pl line 35, <STDIN> line 1.") and I dont know how to fix it or what is working bad, the code is this: (NOTE: I am spanish so i write the comments in my lenguaje, sorry if u dont understand it but i dont think is necesary a traduction)

    #!usr/bin/perl
    #solo funciona para unix/linux/solaris(solaris ni idea)
    #si da el error "Undefined subroutine &main::SYS_statfs called at 
+Filesys/DiskSpace.pm at line XXX", editar syscall.ph
    # (en el perl lib tree) y copiar la linea "SYS_statfs {196;}" fuer
+a del "if (defined &__hp9000s800)" (alrededor de la linea 356)
    use strict ;
    use warnings ;
    use Filesys::DiskSpace ;
    use POSIX ;
    #sistema de archivos/particion a comprobar espacio
    #sacar fecha ;
    my $TIME = strftime("%d/%m/%Y %H:%M:%S", localtime(time) ) ;
    print "+----------+---+----------+\n" ;
    print "+Script made up by 0uts1de+\n" ;
    print "+----------+---+----------+\n" ;
    print "Today is $TIME \n" ;
    print "Write the filesystem/partiton you want to monitor, for exam
+ple /home or /usr \n" ;
    my $monit = <STDIN> ;
    chomp $monit ;
    print "##warning level is by default about a 20 % of free space, i
+f u want to change this##\n" ;
    print "##change the variable warn in the script with a editor like
+ vim or gedit ##\n" ;
    ########## warn string ############
    my $warn = 10 ;
    ###################################
    #consegir caracteristicas de la particion/filesystem (raw)
    my ($fs_type, $fs_desc, $used, $avail, $fused, $favail) = df $moni
+t ;
    my $monit_percentual = (  $avail  /  $avail+$used  ) * 100 ;
    my $final_used = $used / 1000 ;
    my $final_avail = $avail / 1000 ;
    print "$monit is a $fs_type filesystem who has $final_used space u
+sed (in MB) and $final_avail of avalible space (in MB too) \n" ;
    #comparacion con el porcentaje de $monit_percentual
    if ($monit_percentual < $warn) {
            print "Less of the $warn % of the space of the filesystem 
+$monit is avalible for use, consider uninstall unused software \n" ;
    }
    elsif ($monit_percentual eq $warn) {
            print "Be carefull, exactly the $warn % of the space of $m
+onit is usable, consider uninstall unused software \n" ;
    }
    else {
            print "There is a $monit_percentual % of avarible space of
+ the disk \n" ;
    }

In the imput I have the error and the rest, here is:

+----------+---+----------+
+Script made up by 0uts1de+
