See https://github.com/joeyh/git-annex/pull/55.

Please describe the problem.

Solver needs some help when building with +S3 and +Webapp for Homebrew.

What steps will reproduce the problem?

Build git-annex with GHC 8.0.1 and cabal install 1.24.0.0 with --flags=s3\ webapp

What version of git-annex are you using? On what operating system?

6.20160719 macOS 10.11.5

Please provide any additional information below.

git-annex.cabal needs a couple of tweaks to reflect the following known issues:

  1. aws 0.14.0 is incompatible with http-conduit 2.2.0 https://github.com/aristidb/aws/issues/206

  2. esqueleto 2.4.3 is incompatible with persistent 2.5 https://github.com/prowdsponsor/esqueleto/issues/137 https://github.com/prowdsponsor/esqueleto/pull/141 https://github.com/prowdsponsor/esqueleto/pull/139

I assume this will be sorted out upstream, but I don't mind temporarily adding the constraints. done --Joey
