libghc-regex-tdfa-prof 1.2.0-4build3 (powerpc binary) in ubuntu xenial

 A pure Haskell alternative to GHC's Text.Regex module (with some
 enhancements). The Text.Regex module marshalls the data back and forth to
 c-arrays to call libc and this is far too slow (and strict).
 .
 This module parses regular expression Strings using a Parsec parser and
 creates an internal data structure (Text.Regex.Lazy.Pattern). This is then
 transformed a DFA table for matching against the input String or
 FastPackedString. The input string is consumed lazily, so it may be an
 arbitrarily long or infinite source.
 .
 This package provides a library for the Haskell programming language, compiled
 for profiling. See http://www.haskell.org/ for more information on Haskell.
