Hi, I reported and fixed the problem of cabal-debian around detecting GHC built-ins.
cabal-debian searches `package.conf.d' from output of `dpkg -L ghc', for example under `/var/lib/ghc/package.conf.d/', and matches filenames like `base-4.9.0.0.conf'. Under ghc-7.10, checksum suffix exists like `base-4.8.2.0-0d6d1084fbc041e1cded9228e80e264d.conf', but under ghc-8 it does not. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=850920 https://lists.alioth.debian.org/pipermail/pkg-haskell-commits/2017-January/043666.html https://lists.alioth.debian.org/pipermail/pkg-haskell-commits/2017-January/043667.html Please review this fix, and upload. Regards
