I've used `guix import hackage pcg-random` to create the attached pcg-random.scm. When trying to build it using `guix build -f pcg-random.scm`, I get the following error:

starting phase `configure'

Setup.hs:3:1: error:
    Could not find module ‘Distribution.Extra.Doctest’
    Perhaps you meant Distribution.Simple.Doctest (from Cabal-2.4.0.1)
    Use -v to see a list of the files searched for.
