On DragonFly, I needed libdes and libss to build pkgsrc/chat/zephyr. So I 
included:

.include "../../security/kth-krb4/buildlink3.mk"
.include "../../security/libdes/buildlink3.mk"

I don't see a security/kth-krb4/builtin.mk so this would make it always 
install. Is the above correct? Anyone want to add a 
security/kth-krb4/builtin.mk?

(Looking at zephyr source directory, I see it provides some 
kerberos-related downloads for this.)

But it didn't find the headers, so I added:

(It uses kth-krb4's des.h with libdes's library, it looks like.)

Is it okay to commit this for security/kth-krb4/buildlink3.mk? (I don't 
know if it will break others.)

p.s. Another issue is that the Makefile.in for zephyr didn't set
mandir=@mandir@ although it supports that.
