With the apt-cacher package in Debian Lenny, my web interface for the cache statistics wasn't being properly updated. Eventually, I tracked down the problem and figured out that I needed to modify the following section of apt-cacher-report.pl to look like this:
#parse logfile:foreach $logfile_line (@logdata)
{#$logfile_line =~ s/ /\+/g;@line = split /\|/, $logfile_line;
$req_date = $line[0];
# $req_pid = $line[1];# $req_ip = $line[2];$req_result = $line[3];
$req_bytes = 0;
$req_bytes = $line[4] if $line[4] =~ /^[0-9]+$/;
# $req_object = $line[5];
