+### Monkeypatch to work around the broken Rakefile generated by Mkrf <= 0.2.3
+
+# This fixes:
+# * Some weird unnecessary string interpolation
+# * The :install task doesn't work unless you have RUBYARCHDIR in your environment, instead of
+#   falling back to CONFIG['sitearchdir'].
+# * The :install task created the target install directory every time instead of just
+#   declaring a dependency on a directory task
