I tried to fix it int load.c, but failed rubyspec:

However, this one-liner seems to work:
~~~

+++ b/enumerator.c
@@ -2060,6 +2060,7 @@ InitVM_Enumerator(void)

+    rb_provide("enumerator.rb");
     rb_provide("enumerator.so");	/* for backward compatibility */
 }

I'm not sure if we need something similar for complex and rational,
not sure if they were really used via require in the past...
