What happens is that a Haskell package foo you built uses one of the packages provided by Debian, say, bar. Then bar gets updated, then suddenly foo’s dependency on bar is no longer fulfilled, causing these errors. This is confirmed by the above error messages pointing to /root (and not /usr/lib, where Debian packages put the code). Try to run $ ghc-pkg unregister async-2.1.0 and similarly for all broken packages. Or, alternatively, remove all Haskell packages, clear out $ /var/lib/ghc/ and then reinstall.
