My own private bootstrapping (unrelated to stackage) has also revealed these broken packages:

pcre-light categories thyme recursion-schemes yesod-persistent

What build failure are you getting with yesod-persistent? It builds correctly for me. Michael

The problem is a regression between GHC 7.8.0rc2 (what I was testing with) and 7.8.1, which had just been released. There's a GHC ticket open on the issue[1]. Michael [1] https://ghc.haskell.org/trac/ghc/ticket/8978
