Building pendulum takes forever

I've been trying to use pendulum in a Python polyglot native image, however building pendulum takes forever.

docker buildx build . --target pendulum -t pendulum --progress plain

I've stopped the build after 1 hour spent building pendulum, with a single CPU core at max usage.

Here's the Dockerfile to reproduce the issue:

# syntax=docker/dockerfile:1.4

public class Test {
  public static String PYTHON = "python";

  public static String PROGRAM = """
    import pendulum

    now_in_paris = pendulum.now('Europe/Paris')
    print(now_in_paris)
    """;

  public static void main(String[] args) {
    Builder ctxBuilder = Context
      .newBuilder(PYTHON)
      .allowAllAccess(true)
      .option("python.ForceImportSite", "true");

    String pythonPath = System.getenv("PYTHONPATH");
    if (pythonPath != null) {
      ctxBuilder.option("python.PythonPath", pythonPath);
    }

    try (Context context = ctxBuilder.build();) {
      context.eval(PYTHON, PROGRAM);
    }
  }
}
EOF
