You can try running the s5ipc manager and linking perl against libs5ipc.
It's in pkgsrc under sysutils/s5ipc.

Do you have a sample perl script?

Script is

#!/usr/bin/perl
 $file_shmem = "/home/Vishal_Home/bolts";
 $size_shmem = 18640;
  open( F, "./ftok $file_shmem 1 |" );
  $s1 = <F>;
  close F;
  chomp $s1;
  $ipckey = "0x$s1";
  print "IPC-KEY of ($file_shmem) is $ipckey \n";
  $idshm = shmget( $ipckey, $size_shmem, 0666  ) || die "\n Creation of shared memory failed $! \n";
  print "IPC-SHMEM: id $idshm \n";
  shmread( $idshm, $data_shmem, 0, $size_shmem )  || warn "\n\n Error reading shared-memory: $! \n";

Error is-

$ ./myshm.pl
IPC-KEY of (/home/Vishal_Home/bolts) is 0x
System V IPC is not implemented on this machine at ./myshm.pl line 10.
