The pain

$ sudo -u sympa /opt/pkg/bin/perl /opt/pkg/sympa/bin/sympa.pl --help
Line 38, unknown field: bounce_path in sympa.conf
No web archives directory: /opt/pkg/arc

MHonArc is not installed or /usr/bin/mhonarc is not executable.
Language::SetLang(), missing locale parameter
Missing Return-Path in mail::smtpto()
Missing directory '/opt/pkg/bounce' (defined by 'bounce_path'
parameter)
Configuration file /opt/pkg/etc/sympa.conf has errors.

What this error message doesn't bother saying is that it has silently sourced wwsympa.conf as well as sympa.conf, and that the errors come from that file. And no, there is no explicit sourcing of wwsympa.conf in sympa.conf.

God, I hate this software.
