Скачал INN с ftp://ftp.isc.org/isc/inn/inn-2.4.6.tar.gz
1. Распаковал.
2. Начал конфигурировать ./configure
2.1. или просто с конкретными параметрами ./configure --with-syslog-facility=LOG_NEWS --enable-tagged-hash --enable-uucp-rnews --enable-setgid-inews
3. пишу make...и вот тут начинается шляпа....

- пробовал inn-2.4.6.tar.gz, inn-2.4.5.tar.gz, inn-2.4.4.tar.gz, inn-2.4.3.tar.gz
- Что самое удивительное раньше на той же самой freebsd 6.4. работало...
- может, что то не доустановил? или переустановил криво???
