 * `swift-nio-zlib-support` uses `pkgConfig` to find `zlib` on 
 * non-Apple platforms. Details here: 
 * https://github.com/apple/swift-nio-zlib-support/issues/2#issuecomment-384681975
 * 
 * This doesn't play well with Macports, so require it only for non-Apple
 * platforms, until there is a better solution.
