Hi,
I am trying to use the MPI module for the first time. I use the following command:

$>mpirun -np 1 mpitest.pl

and get the following error:

: bad interpreter: No such file or directorypitest.pl: /usr/local/bin/perl

The code is attached below: 
#!/usr/bin/perl

use Parallel::MPI qw(:all);

# Start up MPI
MPI_Init();

# Find out process rank
$my_rank = MPI_Comm_rank(MPI_COMM_WORLD);

# Find out number of processes
$num_procs = MPI_Comm_size(MPI_COMM_WORLD);

$infilename = "sequences.txt";

open(INFILE, $infilename);
@sequences = <INFILE>;
close(INFILE);

$num_seq = $#sequences + 1;

$seq_per_file = int $num_seq / $num_procs;

$start_seq = $my_rank * $seq_per_file;

if ($my_rank < $num_procs)
{
    $end_seq = ($my_rank + 1) * $seq_per_file - 1;
}
else #deal with last processor separately
{
    $end_seq = $num_seq;
}

foreach ($start_seq..$end_seq)
{
    ; #Stuff to do with sequences
    
}

MPI_Finalize();

Any ideas about the problem are welcome.
Thanks
