1. I use FreeBSD for more than 10 years now and know that sometimes ports
    are not updated as soon as I need them, especially if you need to fix
    a security problem quickly. Thus sometimes I need to do what I wrote.

2. I mentioned the problem of security. You did not quote this part of
    my mail in your reply and this is not correct!
