Comment (by snowleopard):

 There are two closed issues on GitHub which seem related to the `unable to
 rename` failure:

 https://github.com/snowleopard/hadrian/issues/203
 https://github.com/snowleopard/hadrian/issues/238

 In both cases we were unable to reliable reproduce the problem and
 eventually closed the issues.

 The `GHC.Prim` issue seem unrelated. Can you reproduce it reliably? If
 yes, it may deserve a separate ticket.
