./configure ошибка с использованием базы кода ssldump

Пытался работать с ssldump
получил код от http://www.rtfm.com/ssldump/ssldump-0.9b3.tar.gz

и следовал инструкциям от INSTALL
но

./configure

бросает

checking host system type... Invalid configuration `x86_64-unknown-linux-gnu': machine `x86_64-unknown' not recognized

checking target system type... Invalid configuration `x86_64-unknown-linux-gnu': machine `x86_64-unknown' not recognized

а потом я попробовал

./configure --with-pcap-lib /usr/lib64/libpcap.so --with-pcap-inc /usr/include/pcap

но получаю эту ошибку.

configure: warning: /usr/lib64/libpcap.so: invalid host type
configure: warning: /usr/include/pcap: invalid host type
configure: error: can only configure for one host and one target at a time

а потом

./configure --enable-64bit=x86_64-unknown-linux-gnu --with-pcap-lib /usr/lib64/libpcap.so --with-pcap-inc /usr/include/pcap

configure: warning: /usr/lib64/libpcap.so: invalid host type
configure: warning: /usr/include/pcap: invalid host type
configure: error: can only configure for one host and one target at a time

и я попробовал все те с командами с обновленными файлами .sub и .guess, но все еще не повезло.
