libghc-unordered-containers-prof binary package in Ubuntu Precise i386

 This package provides a library for the Haskell programming language,
 compiled for profiling.
 See http://www.haskell.org/ for more information on Haskell.
 .
 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.
