[squid-users] access logging to a Named Pipe

I'm trying to log to a FIFO named pipe on FreeBSD 4.4-R, squid-2.5.PRE5.
I did "mkfifo /var/log/squid/fifolog", "chown squid:squid
/var/log/squid/fifolog",
configured Squid "cache_access_log /var/log/squid/fifolog"

I ran a small SUID perl script with owner "squid" on a virtual terminal,
and tried to start Squid. I noticed in cache.log
2002/04/15 19:50:13| logfileOpen: /var/log/squid/fifolog: (6) Device not
configured

However, I can successfully "cat file>/var/log/squid/fifolog" as root
or as a user who has rights to write to the pipe!
The contents is printed on a virtual terminal.
Note, that Squid can successfully log to a normal file
/var/log/squid/access.log

What is wrong with in logging?
Should Squid logging function to be corrected?

I cannot find a solution:

My perl script:
#!/usr/bin/perl -w
#
# Squid script

use strict;
no strict 'refs';
use Fcntl qw(:DEFAULT :flock);
use CGI::Carp qw (fatalsToBrowser);

BEGIN {
  my $str=$0; $str=~ s|[^/]*$||; # Delete the filename: some non-"/", end of
line
  unshift (@INC, $str); #Dir of the current script
  use CGI::Carp qw(carpout);
  my $LOG=$str.'error-perl.log';
  open($LOG, ">>$LOG") or die "Can't open $LOG: $!\n";
  carpout($LOG);
}

$|=1; # Autoflush the output buffer

#my $DATA='./fifo';
my $DATA='/var/log/squid/fifolog';
open($DATA, "<$DATA") or die "Can't open $DATA: $!\n";

my $line;
while ($line=<$DATA>)
{
  print scalar(localtime).";Line received:\n$line";
  sleep(1);
}

close($DATA) or die "Can't close $DATA: $!\n";
