build fail with latest 8.1 sources

Sat Nov 12 23:16:57 UTC 2016

I’ve seen a very recent commit that mentioned bumping a TH bound.  Maybe pull, make clean and try again?

Subject: build fail with latest 8.1 sources

Hi everyone,

I'm trying to build the latest 8.1 sources on a Mac running El Capitan.  I'm getting an error I'd never seen before and wonder if anyone has any pointers of how I might fix things.  I blew away my GHC, re-cloned from github, reconfigured and I still get the same error.

The following are the relevant output lines; the problem is that the template-haskell version doesn't seem to match.  I'm not sure whether this is coming from the template-haskell in 8.1 or in 8.0.1 (which I'm using to build 8.1), but checking the latter I have version 2.11.0.0 which I assume should be sufficient.

John
