Looking for Libraries

Hi all, This is probably a long shot, but I am looking for a few libraries and don't want to put effort into something that has already been done. Is there a high level Haskell graphics library that would give functionality similar to gnuplot? I know I could build one myself, but I hate graphics programming. Does anyone have an FFI interface to LAPACK? Does anyone have an FFI interface to a free linear program solver? Or, a Haskell implmentation of the two-step simplex method? (I sold my copy of Chvatal's book in college for beer money). Thanks. -- Matthew Donadio (m.p.donadio@ieee.org)
