When I run my perl script that uses threads I get the following error, a google search shows only 2 results, 1 is russian and I can't read it, the other is a blog that no longer seems to have the issue listed.

Can't locate auto/threads/is_joinable.al in @INC (@INC contains: /etc/

Currently I am trying to make sockets and threads work as I intend before writing the rest of the code, so it is a pretty simple script so far.
here is OEFS.pl:

#!/usr/bin/perl
use strict;
use IO::Socket::UNIX;
use threads;
use threads::shared;

my $LSocket;
my @Links;
my $NumConnections = 32;  #allow for 32 connections
my @Connections = (1 .. $NumConnections);
my @StructDs : shared;
my @StoreDs : shared;

sub ConThread($);

MAIN:
{
    die("The first and only requirement should be the name for this OE
+FS instance, and is required!\n") if (!($ARGV[0]));
    #Start the listener
    mkdir("/tmp/OEFS/") if (!(-e "/tmp/OEFS"));
    unlink('/tmp/OEFS/' . $ARGV[0]);
    $LSocket = new IO::Socket::UNIX('Listen' => 1, 'Local' => '/tmp/OE
+FS/' . $ARGV[0]);
    die("$!\nUnable to create listen socket!\n") if (!($LSocket));
    my $Link;
    my $IDX;
    print("Listening...\n");
    while ($Link = $LSocket->accept())
    {
        #Clean out old threads
        foreach my $I (1 .. $NumConnections)
        {
            if (($Links[$I]) && ($Links[$I]->is_joinable()))
            {
                $Links[$I]->join();
                unshift(@Connections, $I);
                print("Connection #$I now free\n");
            }
        }
        
        print("Incomming Connection\n");
        $IDX = pop(@Connections);
        
        if ($IDX)
        {
            print("Using connection #$IDX\n");
            print("Spawning Thread\n");
            #New thread.
            $Links[$IDX] = threads->create(\&ConThread, $Link);
        }
        else
        {
            print("Too many connections\n");
            print $Link "Maximum number of connections has been reache
+d.\n";
            $Link->close();
        }
    }
}

sub ConThread($)
{
    my ($Socket) = @_;
    print $Socket "Ready\n";
    $Socket->close();
    return;
}

here is the program I am using to access OEFS.pl through the socket, the error occurs when I run it a second time to make sure the first connection is cleared:

#!/usr/bin/perl
use strict;
use IO::Socket::UNIX;

my $TheSocket;

MAIN:
{
    die("The first and only requirement should be the name of the OEFS
+ instance, and is required!\n") if (!($ARGV[0]));
    $TheSocket = new IO::Socket::UNIX('Peer' => '/tmp/OEFS/' . $ARGV[0
+]) || die("$!\nUnable to connect!");
    print "Socket says: " . <$TheSocket> . "\n";
    $TheSocket->close();
    exit(0);
}
