Please report the problem to apache at FreeBSD.org [maintainer] and attach the
"/usr/ports/www/apache20/work/httpd-2.0.64/config.log" including the output
of the failure of your make command. Also, it might be a good idea to provide
an overview of all packages installed on your system (e.g. an `ls
/var/db/pkg`).
