that seemed to solve the problem I was experiencing with bind. 
Christopher's suggestion of running it without the -l option also 

I am now forging ahead and using Cache::Memcached (1.14) with Perl 
(5.8.0) on OS X (10.3.1) but my results so far are not good. Is there a 
more suitable place to discuss the Perl API?

Basically, I am trying something like this:

use strict;
use Cache::Memcached;

my $memd = new Cache::Memcached( { servers => [ "" ] } );
my $key = "test_key";
my $data = $memd->get($key);
if ($data) {
     print STDERR "existing data\n";
else {
     $data = { hello => 'world' };
     my $memd_set = $memd->set($key,$data);
     print STDERR "memd set failed\n" unless ($memd_set);

What I am seeing is "Use of uninitialized value in string eq at 
/opt/perl/lib/site_perl/5.8.0/Cache/ line 439". This is the 

return $res eq "STORED\r\n";

Essentially, the return value from the call to 
_oneline($self,$sock,$line) on line 427 is undefined, so I still have 
problems in there somewhere. It also takes about 2 seconds to complete 
that subroutine call (or is this what Sean refers to as terrible kqueue 
performance under non-server OS X?) or maybe what I am seeing is 
actually one second for select_timeout.

What is the best way to go about debugging this? Should I be trying to 
run memcached without the -d switch in some sort of verbose mode? Or 
should I hack Cache/ and see what I can print out?

Thanks again,
