Comment (by Neidon):

 > Have you been able to reproduce this after wiping your .stack directory?

 No. I did `rm -rf ~/.stack`, then rebuilt the whole project from scratch
 `stack build --install-ghc` and the problem was gone.

 I've tried this just now on the same machine and I'm also getting missed
 interface files, albeit for a different package.

 {{{
 /tmp/stack13960/cpphs-1.20.4/Language/Preprocessor/Cpphs/ReadFirst.hs:21:1:
 error:
         Failed to load interface for ‘System.Directory’
         There are files missing in the ‘directory-1.3.1.0’ package,
         try running 'ghc-pkg check'.
         Use -v to see a list of the files searched for.
 }}}

 So I don't know how to reproduce this anymore. For future reference, it
 would be nice to know what I should include in the dumps of the computer's
 state aside from `~/.stack` and the project directory, but for now this
 bug should probably be closed and reopened only if someone else encounters
 it.
