The same for Java, since its ecosystem has an allergy to calling native (non-JVM) code, to the point of rewriting perfectly good libraries in Java. When they do call native code, it's often in horrible ways (like copying a native library from within the JAR file to a temporary directory, and loading it from there, the JAR file coming with pre-compiled native libraries for all possible operating system and architecture combinations). So the Java package managers mostly focus on Java (and other JVM languages) code building and delivery.
