Loading the default OpenSSH configuration files is a feature many people relies on. It is too late to change that behavior now. I will add a flag to dissable it, though.
In any case, could you show me your configuration file? I would like know which configurations are breaking Net::OpenSSH. There may be some way to workaround your specific issues.
