Portupgrade and postfix error

[Nick Kraal]

I am trying to solve two problems. The first is an error message running 
portupgrade. I have 'make deinstall' and 'make reinstall' for both 
ruby18 and portupgrade ports. No luck.

The second is a postfix/sendmail error message. I have disabled sendmail 
in the /etc/rc.conf options and was playing around with postfix. I have 
deleted postfix and still get error messages.

Would appreciate any hints and pointers.

Thanks in advance.
