Build failure from mtl-compat overhaul about haxr HOT 5 CLOSED

Same here: http://hydra.cryp.to/build/579020/log/raw.

from haxr.

Hmm, thanks for the report. My travis build is succeeding (https://travis-ci.org/byorgey/haxr/builds/51775356); what would be the difference?

In any case, what is the current best practice with regard to mtl/transformers stuff? I have been somewhat out of the loop.

from haxr.

My guess is that you're building with transformers 0.4. The best practice here is likely to just add transformers-compat and/or mtl-compat to your build-depends, which should solve this problem.

OK, I just uploaded haxr-3000-10-4-2 which adds an mtl-compat dependency. As far as I understand this should fix the problem; but since my travis build was succeeding previously, I can't really tell. Please let me know whether I can close this ticket. Thanks!

@byorgey I'll close the issue for now, and if there are problems with future Stackage builds, I'll reopen. Thanks for the quick response!
