libghc-unordered-containers-prof binary package in Ubuntu Trusty amd64

 It contains efficient hashing-based container types. The containers
 have been optimized for performance critical use, both in terms of
 large data quantities and high speed.
 The declared cost of each operation is either worst-case or
 amortized, but remains valid even if structures are shared.
 .
 This package provides a library for the Haskell programming language, compiled
 for profiling. See http://www.haskell.org/ for more information on Haskell.
