Comment (by snoyberg):

 I've reproduced the same error whether I use `cabal install` or `cabal
 install -j`. I did the building in a fresh hsenv with a standard cabal
 config file: [http://lpaste.net/105744]. I got the same issues from:

 1. The build I just made.
 2. Herbert's Ubuntu PPA.
 3. A binary that Austin sent me.

 I'm running Ubuntu 12.04, 64-bit. I got the same results on my Stackage
 server as well:
 [http://jenkins.stackage.org/job/Stackage/36/ghcversion=7.8.3/console].
