Can you give this a try?

------------------------------------------
#!/usr/bin/perl -w
use strict;
$|++;
use Apache::Scoreboard;
my $image=Apache::Scoreboard->fetch("[a scoreboard location]");
for (my $parent = $image->parent; $parent; $parent = $parent->next) {
     my $pid = $parent->pid;
     print $pid,': ',(`/bin/ps --no-headers $pid` || "Process Not Found\n" );
}
------------------------------------------
(How is this different from iterating @{$image->pids()}?)

Unless I'm completely misunderstanding the man page for Apache::Scoreboard, 
this should spit out a list of Apache processes.  I'm getting stuff like 
this instead:

(incomplete listing...)
51825: Process Not Found
17057: 17057 ?        S      0:01 /usr/local/apache-perl-1.3.33_5.8c/bin/httpd
51581: Process Not Found
17139: 17139 ?        S      0:01 /usr/local/apache-perl-1.3.33_5.8c/bin/httpd
52940: Process Not Found
16615: Process Not Found
51785: Process Not Found
16632: Process Not Found
47713: Process Not Found
16633: Process Not Found

I'm not sure if it's related, but this:

------------------------------------------
#!/usr/bin/perl -w
use strict;
$|++;
use Apache::Scoreboard;
my $image=Apache::Scoreboard->fetch("[a scoreboard url]");
for (my $parent = $image->parent; $parent; $parent = $parent->next) {
     my $server = $parent->server; #Apache::ServerScore object
     print $server->vhost,"\n";
}
------------------------------------------

still segfults on my machine.  VMonitor is working fine, though.
