libghc-happstack-prof binary package in Ubuntu Trusty ppc64el

 Happstack is a web framework written in Haskell; it provides a rich
 collection of types and functions for routing Requests, generating
 Responses, working with query parameters, form data, and cookies,
 serving files and more.
 .
 This package contains the profiling libraries compiled for
 GHC. Anyway, it is just a stub, depending on the package that
 actually provides the Happstack server.
