>Description:
building src/libexec/telnetd fails if MKKERBEROS4 is set to 'no'
(for both HEAD and netbsd-2-0 sources): I'm getting undefined
references to des_new_random_key, des_ecb_encrypt, des_key_sched and
des_init_random_number_generator. These symbols seem to be in libdes;
however, -ldes is added to LDADD only if Kerberos IV is built.
>How-To-Repeat:
$ cd src/libexec/telnetd && make MKKERBEROS4=no dependall
