+## Transitional Hack ####
+#
+#  RDoc was initially distributed independently, and installed
+#  itself into <prefix>/lib/ruby/site_ruby/<ver>/rdoc...
+#
+#  Now that RDoc is part of the distribution, it's installed into
+#  <prefix>/lib/ruby/<ver>, which unfortunately appears later in the
+#  search path. This means that if you have previously installed RDoc,
+#  and then install from ruby-lang, you'll pick up the old one by
+#  default. This hack checks for the condition, and readjusts the
+#  search path if necessary.
+
+def adjust_for_existing_rdoc(path)

+  $stderr.puts %{
+  It seems as if you have a previously-installed RDoc in
+  the directory #{path}.
+
+  Because this is now out-of-date, you might want to consider
+  removing the directories:
+
+    #{File.join(path, "rdoc")}
+
+  and
+
+    #{File.join(path, "markup")}
