--- Comment #20 from Jens Petersen petersen@redhat.com --- We will move to a new Cabal when we move to ghc-7.8 (koji builds don't use cabal-install of course). :)
For good measure I also tried 5.20140717 on f20 koji and it also failed. http://koji.fedoraproject.org/koji/taskinfo?taskID=7193337 But since it builds fine locally I suspect it should be something else, I wonder if something changed in the koji env lately? Also 1MB is not very much... quite strange.
I see it build okay in debian unstable: https://packages.debian.org/jessie/git-annex which I think is still on ghc-7.6.3 as well.
Anyway yeah maybe moving to ghc-7.8 will help to fix this perhaps. It would be good to version bisect this though, since 5.20140221 still builds but 5.20140717 isn't configuring.
