libghc-fail-prof 4.9.0.0-1build2 (s390x binary) in ubuntu zesty

 This package contains the "Control.Monad.Fail" module providing the MonadFail
 class that became available in base-4.9 for older base package versions.
 .
 This package turns into an empty package when used with GHC versions
 which already provide the "Control.Monad.Fail" module to make way for
 GHC's own "Control.Monad.Fail" module.
 .
 This package provides a library for the Haskell programming language, compiled
 for profiling. See http://www.haskell.org/ for more information on Haskell.
