I have been trying to understand what is wrong, but haven't found
anything. My best guess right now is that this is a GHC bug that
manifests due to the time64 transition.

Oddly enough, if we run 'build' again it succeeds.

My course of action for now is:
  * Upload a workaround for haskell-pandoc that runs 'build' twice, so
    we can finish with this transition
  * Upgrade to GHC 9.6 with the next transition, with the hope that this
    bug is fixed there
  * If not, report this upstream
