Failing to build on stackage nightly

We are seeing errors in building for stackage nightly with the following error:

We have taken log-warper out of nightly. Once the issue has been fixed would you raise either a stackage PR or issue so we can get it restored to stackage.

@cdornan Thanks a lot for reporting this! I really appreciate your effort. Sorry for such building problems. This is now fixed both in master and 1.3.2 version on Hackage. It builds now with nightly-2017-10-13 resolver.

He, @cdornan! Does the fix work for you? I don't see log-warper in stackage nightly currently... Let me know if I need to fix something else, please :)

[chshersh]

Outdated. Newer version is already in stackage nightly. And has another issue...
