Why the change ?
djbdns, which provides the DNS client libraries used by skadns, is not free, or open source software, as you name it. Honestly, I don't care: it's excellent software, and that's all that counts to me. But some people do not want to have anything to do with non-free software, and that could prevent them from using skadns. Besides, it was unclear whether you, or I, could distribute precompiled skadns binaries.
On 2002, July 4th, D. J. Bernstein put the djbdns client library into the public domain. So I took the source code and included it in skalibs, which centralizes other public domain and otherwise free-licensed code that I use in all my projects. Now the legal state of skadns is very clear: it's not dependent on any non-free code, it's BSD-licensed, it's only linked with public-domain and non-virally free-licensed libraries, and you can distribute skadns binaries, provided that your C compilation chain allows it.
