I confirm. I tried "apt-get install debbindiff --install-recommends", which should be equivalent, in a pbuilder --login and it did not reproduce the issue either. I also tried installing ghc and its depends in two steps to see whether a missing ldconfig invocation after ghc unpack could be a cause. From my pbuilder --login this succeeded without issue. Now I tried again from a fresh debootstrap sid. First install all of ghc's depends. Then install ghc: | # apt-get install ghc | Reading package lists...
