It's not easy to remove zziplib from the distribution package, the author of Milkytracker has modified zziplib in order to integrate it. To make zziplib an external dependency would require some rethinking/rewriting of Milkytracker's decompression support, something the author is reluctant to do as he doesn't see it as a problem - he'd rather remove the zip support for Linux/FreeBSD/etc rather than fix this.

Any chance you could contact the upstream and request such ./configure flag? Like, --disable-bundled-libs or such, I think we could live without zip support and just let the users know about it.
Patched it to use system zlib (without revbump).
