rune.top not loading

[nilsbecker]

in 1.0.0alpha2, i get the following in utop:

 #require "rune.top";;
Error: Reference to undefined compilation unit `Parse'
Hint: This means that the interface of a module is loaded, but its implementation is not.
      Did you mean to load a compiled implementation of the module
      using #load or by passing it as an argument to the toplevel?

loading plain "rune" works fine. same issue for "nx.top"
