The Doctor,
There is in your logs posted to can.canet.stats:

Do you use an official release of Perl or a development one?
Anyway, we are using the following code in a few Perl scripts:
if ($use_syslog) {
if ($Sys::Syslog::VERSION < 0.15) {
eval "sub Sys::Syslog::_PATH_LOG { '/dev/log' }" if $^O eq 'dec_osf';
Sys::Syslog::setlogsock('unix') if $^O =~
/linux|dec_osf|freebsd|darwin/;
}
openlog('controlchan', 'pid', $INN::Config::syslog_facility);
}
Unfortunately, version.pm which would allow to use:
version->parse("$Sys::Syslog::VERSION") < version->parse("0.15")
is not present in Perl 5.8.0 (it was introduced in Perl 5.9.0).
I do not think we should drop Perl 5.8.0 compatibility because of that
(Perl 5.10.0 is "fairly" recent).
Does anybody know a proper way to compare module versions in Perl?
I had in mind just taking the part before "_" and go on comparing
the numbers, but it is not very satisfying...
I also see:

Do you know what causes that, The Doctor?
And do you really need overchan?

There are tons of similar lines at the end of your Usenet daily report.
I believe they should not be there. I'll have a look to see why
they end up in the daily report.
